Answer 13

SORRY i d k

Answer 14

if you know the diameter, find the radius...

can you do that

Answer 16

when they ask for an exact value, you need to leave the answer in terms of pi...

so the formula becomes

\[V = \frac{4 \times r^3}{3} \pi\]

just don't multiply by pi

Answer 17

you are given the diameter, halve it to get the radius....

so what is half of 30..?

Answer 18

15

Answer 19

great so now calculate

\[V = \frac{4 \times 15^3}{3}\]

what do you get..?

Answer 20

4500

Answer 21

great so the answer is

\[V = 4500 \pi \]

Answer 22

just add the units

Answer 23

thankyou so much
