A cylinder with a radius of 5 feet and height of 2 feet.

What is the surface area of a cylinder with a radius of 5 ft and a height of 2 ft?
60Pi ft2
70Pi ft2
96Pi ft2
150Pi ft2

Answers

Answer 1

Answer:

B, 70pi ft2

Step-by-step explanation:

The equation to find surface area of a cylinder is 2(pi)(r)(h)+2(pi)(r)^2. So now plug the numbers in.. 2(pi)(5)(2)+2(pi)(5)^2 now, simplify. 20pi+50pi= 70pi ft2.

Answer 2
the correct answer is 70Pi ft2

using this formula: A=2πrh+2πr2, substitute r for 5 and h for 2 and put it like this:

a = 2π x 5 x 2 + 2π x 5 squared

2 x 5 x 2 = 20

a = 20π + 2π x 5 squared

5 squared = 25

a = 20π + 2π x 25

multiply 2 by 25 which equals 50

a = 20π + 50π

add 20 and 50 which gives you 70 making the final answer: a = 70π ft 2

Using the formulas:

A=πr2

d=2r

Solving for A

A=1

4πd2=1

4·π·62≈28.27433ft²

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)

28 out of 50 8th graders said they prefer snow to rain. 42 out of 58 10th graders said they prefer snow. did a larger percentage of 8th graders or 10th graders prefer snow?

explanation please

Answers

A larger percentage of 10th graders preferred snow.

Answer:

10th graders prefered snow then 8th graders did.

Step-by-step explanation:

Hey I hope I will be able to help!

To find out the percentage we need to divide the fractions-

28 divided by 50 = 0.56 and in percentage form its 56%

42 divided by 58 = approximately 0.72 which is 72%

56% < 72%

72% is obviously greater so 10th graders prefer snow more than 8th graders do.

Answer:

C = -13.78

Step-by-step explanation:

Answer:

c = -13.78

Step-by-step explanation:

21.2x + c =5.3(4x - 2.6)

Use distributive property: a*(b + c) =  (a*b) + (a * c)

21.2x + c = 5.3*4x - 5.3*2.6

21.2x + c  = 21.2x - 13.78

Now to find the value of c, isolate 'c'. So, subtract 21.2x form both sides

21.2x + c - 21.2x = 21.2x - 13.78 - 21.2x

c = -13.78
