Answer 2

Formula:

\(V = \pi d\)

Answer 3

Where 'd' is the diameter

Answer 4

So just plug in 16 for 'd'.

Answer 5

\[C=2πr \] wouldnt this be the formula?

Answer 6

so 32

Answer 7

Yes, but 2 times the radius is the same as the diameter.

\(C = 2 \pi r\)

or

\(C = \pi d\)

Answer 8

is the same

Answer 9

ah ok :) continue on then

Answer 10
