Answer 4

The diameter is 20.

d = 20

Answer 5

the radius is half of the diameter

r = d/2

r = 20/2

r = 10

Answer 6

now use the formula

\[\Large V = \pi*r^2*h\]

Answer 7

r = radius
h = height

so,

r = 10
h = 2

Answer 8

Omg thank you so much

Answer 9

You deserve a medal

Answer 10

glad to be of help

Answer 11

so is the answer 100 x 2?

Answer 12

@jim_thompson5910

Answer 13

that's 200 and don't forget the pi

Answer 14

your exact volume in terms of pi is \[\Large V = 200\pi\]

Answer 15

then use \[\Large \pi \approx 3.14\] to get the approximate volume

Answer 16

use more digits of pi to get a more accurate approximation

Answer 17

Okay thank you . You are so awesome
