Question

A cylinder has a height of 5 centimeters and a radius of 2.3 centimeters. What is the volume of this cylinder?

A
3.32 cm3

B
16.62 cm3

C
83.10 cm3

D
180.64 cm3

Answer 1

i got 83.10 ony my test and used a calculator so it's right

Explanation:

Answer 2

C) 83.10 cm³

Explanation:

The formula for a cylinder's volume is V = πr²h. First, plug in everything that you know.

V = π(2.3)²(5)

Now, square 2.3 This is the same as 2.3 x 2.3 and will give you 5.29.

V = π(5.29)(5)

Multiply 5.29 x 5.

V = 26.45π

Now multiply 26.54 x π. Use 3.14 for π.

V = 83.053

All the answer choices have two decimal points behind them, so you would round your answer to the nearest hundredth.

V = 83.10 cm³
