PLEASE HELP ME

Answer 1

Do you know the formula of the volume of a cylinder?

Answer 2

3.14

Answer 3

No no :)

The vormula to find the volume of a cylinder is \(\rm V~=~3.14\times r^2 \times h\)

The radius ( r ) is half of the diameter, which is 12in, so our radius is 6in, and our height ( h ) is 48 in
So
r = 6
h = 48

Now plug in the information in the formula

\(\rm V~=~3.14\times r^2 \times h\)

\(\rm V~=~3.14\times 6^2 \times 48\)

First solve the eponent, which is \(\rm 6^2\) which is \(\rm 6 \times 6\)

So what is \(\rm 6 \times 6\)?

Answer 4

36

Answer 5

Good! So we plug in 36 where \(\rm 6 \times 6\) was in the equation!

\(\rm V~=~3.14\times 36 \times 48\)

Now multiplying from left to right, we must multiply 3.14 and 36

So what is \(\rm 3.14 \times 36\)?

Answer 6

113.04

Answer 7

Correct! So we plug in 113.04 where \(\rm 3.14 \times 36\) in the equation!

\(\rm V~=~113.04 \times 48\)

Can you solve the rest?

Answer 8

D

Answer 9

@sammixboo thanks

Answer 10

Hmm hold on a second

Answer 11

No it isn't D :( All you need to do is multiply 113.04 x 48

Answer 12

And she left. Mwuahah I guess that is what she gets :(
