Find the area of a circle with a diameter of 6 feet. Find both the exact area and the area rounded to the nearest

Answers

Answer 1

Answer is =28.27433ft²

Step-by-step explanation:

A≈28.27ft²(Answer)

Diameter

Using the formulas:

A=πr2

d=2r

Solving for A

A=1

4πd2=1

4·π·62≈28.27433ft²

Answer 2

To answer this question we need to use a basic formula to find the area of a circle which is:
pii*radius*radius

Steps:
1. Find the radius

Divide 6 (diameter) by 2 since 2 radius makes up a diameter, so you would get 3 has the radius.

2. Substitute the values

3.14 * 3*3
Which equals 28.26.

Answer:
Exact area—28.26 ft (squared)

Rounded to the nearest tenth—28.3 ft (squared)

Hope this helps!!

Answers

Answer:

125.6m^2

Step-by-step explanation:

Let R be the greater radius and r be the smaller radius

Area of the sidewalk = R^2 - r^2 - This can be the expression

= 3.14

=(R^2-r^2)

=(11^2-9^2)

=(121-81)

= 40

= 3.14 x 40

An inequality is given, where r is a positive rational number.

r • q/r < 0

Which inequality must also be true?

A.) q < 0

B.) q > 0

C.) q < - r

D.) q/r < - r

What is the decimal equivalent of 8%

Options: 0.8
8.0
0.08
0.008

Answers

answer:

b) 0.08

step-by-step explanation:

to find which answer choice was correct i turned 8% into a fraction-

**i did this by putting 8 over 100-

8/100 from here i treated the fraction as if we were dividing

so if you wanted to you can re-write the fraction as 8÷100

8÷100

=0.08

0.08=8%=8/100

0.08 is the correct answer

good luck :)

Answers

Answer:

0 < x ≤ 1 would be f(x) = 1

1 ≤ x ≤ 2 would be f(x) = x

2 < x ≤ 3 would be f(x) = 3

3 < x ≤ 4 would be f(x) = 4

step-by-step explanation:

0 < x ≤ 1 is over the line 1

1 ≤ x ≤ 2 x is the slope of 1

2 < x ≤ 3 is over the line 3

3 < x ≤ 4 is over the line 4

Not mine just copied the answer from the comment of the person who gave no help all the credit goes to the person who commented the correct answer

Answer:

Answers above are correct for Plato/Edmentum users

1 ≤ x ≤ 2 = f(x) = x

0 < x ≤ 1 = f(x) = 1

3 < x ≤ 4 = f(x) = 4

The models below are shared to show 4/8 and 2/4. What do the models show about these fractions

Answers

Answer:

I do not see the model, but based on what you are telling me, I believe that both the fractions are equal is what is being shown. They are, in other words, equivalent fractions

Answer:

The models show that both fractions are equivalent.

Step-by-step explanation:

The model shows they have the same value but are just divided in different ways. Also, if you reduce 4/8 you get 2/4 meaning they are equivalent.

Which measure of spread is the most appropriate for the data set represented by the graph?
A. range
B. quartiles
C. interquartile range
D. mean absolute deviation
E. either range or interquartile range

Answers

The answer is D! I hope this helps..

The most appropriate for the data set represented by the graph is mean absolute deviation.

What is Mean absolute deviation (MAD)?

It is a measure of variability or variation that indicates the average distance or average absolute distance between each data point or data value and the mean of a data set

We can calculate the variability of a data set by different measure thay include range, interquartile range, mean absolute deviation, standard deviation, etc.

Quartiles or ranges may be useful but they are limited as they tend to skip a lot of data in the group.

While, absolute deviation can help us get a more representative idea of spread for a data set like the one given in this question, where the elements have close difference.

Hence, the most appropriate for the data set represented by the graph is mean absolute deviation.

Answer: Hello, There! your Answer is Below

40 Is your Answer

Step-by-step explanation:

Step 1: Our output value is 80.

Step 2: We represent the unknown value with XStep 3:

From step 1 above,$80=100

Step 4: Similarly, x=50

Step 5: This results in a pair of simple equations:This results in a pair of simple equations:

$80=100\(1)

$x=50(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

80/x = 100%/50%

Step 7: Again, the reciprocal of both sides gives

x/80 = 50/100

x=40$

Therefore, 50%of 80i s 40
