Answer and Step-by-step explanation:
The area formula for a Circle is:
A = [tex]\pi r^2[/tex]
Diameter is equal to the radius times 2.
So, divide the diameter to get the radius.
6 divided by 2 equals 3.
Now, plug it into the formula.
[tex]A = \pi (3)^{2}[/tex]
A = [tex]9\pi[/tex]
Plug this into your calculator by multiplying 9 by pi.
We get the answer to be 28.3 when rounded to the nearest tenth.

Gerard bought 100 feet of fence to make a pen for his sheep. He decided to build the fence up
against his barn, as shown in the picture below. He wants to MAXIMIZE the amount of area of the pen.
What should the dimensions be? (HINT: Area = length x width)
Answer:
Step-by-step explanation:
P = 2b + a = 100
A = b * a
a = 100 - 2b
A = b(100 - 2b) = 100b - 2b^2
dA/db = 100 - 4b
100 - 4b = 0
b = 25
a = 50

The perimeter of a rectangle is 48cm. its length is 4 cm. what is its width?
Answer:
P = 48
4 + 4(two given lengths) = 8
48(perimeter) - 8(length of two given lengths) = 40(length of two unknown sides)
40(length of two unknown lengths) divided by 2(two missing sides) = 20 cm

If A and B are mutually exclusive, and if P(A) = 23% and P(B) = 16%, what is P(A or B)?
P(A or B)=[%
Answer:
P(A or B) = 39%
Step-by-step explanation:
If A and B are mutually exclusive, they cannot occur at the same time, therefore their probabilities are added. This means P(A or B) = P(A) + P(B) = 23% + 16% = 39%

A cube-shaped box has a volume of 1/8 of a cubic meter. What is the perimeter of each of its
faces?
Given:
The volume of a cube-shaped box is [tex]\dfrac{1}{8}[/tex] cubic meter.
To find:
The perimeter of each of its faces.
Solution:
Let "a" be the side length of the cube shaped box. Then the volume of the box is:
[tex]V=(side)^3[/tex]
[tex]V=a^3[/tex]
It is given that the volume of a cube-shaped box is [tex]\dfrac{1}{8}[/tex] cubic meter.
[tex]a^3=\dfrac{1}{8}[/tex]
Taking cube root on both sides, we get
[tex]a=\dfrac{1}{2}[/tex]
Now, the perimeter of each face of a cube is:
[tex]P=4a[/tex]
Where, a is the side length of the cube.
Putting [tex]a=\dfrac{1}{2}[/tex], we get
[tex]P=4\times \dfrac{1}{2}[/tex]
[tex]P=2[/tex]
Therefore, the perimeter of each face of a cube-shaped box is 2 meters.
Answer: It's 2 meters
14 In a book, 98% of the pages contain text, diagrams on both. If 88% of the pages
contain text and 32% contain diagrams, what percentage contain
a.neither text nor diagrams
b. only diagrams
c.only text
d.both text and diagrams?
Answer:
2%
10%
66%
22%
Step-by-step explanation:
For the first one we just need to find the compliment of the union (.98) which is .02
Union formula:
A∪B=A+B-A∩B
We will let T= text and D= diagram
we know that
.98=.88+.32-T∩D
Solve and find that T∩D= .22
Only diagram: .32-.22= .1
Only text: .88-.22= .66
Text and diagrams is the intersection we found earlier or .22

Can someone help me with this
Answer:
C
Step-by-step explanation:
1. Absolute values are in the shape of a V, so the answer is automatically C.
2. If you did not know that, you can see that the graph is a function because it passes the vertical line test. This rules out option A. By looking at the graph, you can see it passes the x-axis twice, meaning that it has 2 x-intercepts. This rules out option B. X-intercepts always have a y-coordinate of 0, so we can rule out option D. The only option left after this is C.

The equation for the speed/distance of a tornado is
s = 93 log(d) + 65.
If the speed is 310 mph, what is the distance?
Answer:
430.93 miles (rounding to the nearest hundredth)
Step-by-step explanation:
s = 93 log(d) + 65
310 = 93 log(d) + 65
245 = 93 log(d)
2.634408602 = log(d)
10^2.634408602 = 10^log(d)
430.9318583 = d
Therefore, if the speed of the tornado is 310 mph, then its distance is about 430.93 miles.

Solve by using substitution.
=3−8
=−4
Answer:
I'm going to assume that you meant y=3x-8 and y=-4
This means that you would substitute -4 into the spot of y which gives you -4=3x-8. Once solved you would receive x=4/3.
Hope I helped have a nice day :)

What is the volume of the cylinder below? 9- 7 - 5 OA. 1757 units3 B. 2257 units3 C. 357 units3 D. 70n units3
Answer:
175 pi ^3
Step-by-step explanation:
The volume of the cylinder is 175π cubic units or 175π units³ if the radius of the base r is 5 units and the height of the cylinder h is 7 units option (A) 175π units³ is correct.
What is a cylinder?In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.
We know the volume of the cylinder is given by:
[tex]\rm V = \pi r^2 h[/tex]
Volume can be defined as a three-dimensional space enclosed by an object or thing.
As we know,
We can find the volume of the cylinder by using the given formula:
[tex]\rm V = \pi r^2 h[/tex]
The radius of the base r = 5 units
The height of the cylinder h = 7 units
[tex]\rm V = \pi (5)^2 (7)[/tex]
V = 25x7π
V = 175π cubic units
Or
V = 175π units³
Thus, the volume of the cylinder is 175π cubic units or 175π units³ if the radius of the base r is 5 units and the height of the cylinder h is 7 units option (A) 175π units³ is correct.
