Question

Find the Volume of a hemisphere with a diameter of 17 cm. Use pi = 3.14 and round to the nearest hundredth.

I need someone to show me how to actually do this (:

Answer 1

4/3 pi r^3 is for sphere
for hemisphere, it would be : 1/2(4/3 pi r^3)=4/6 pi r^3

Answer 2

thats the formula?

Answer 3

Yes

Answer 4

ok lemme try this lol

Answer 5

remember you are given diameter(twice the radius)

Answer 6

ok so now i am at 4/6 *3.14* 8.5^3

Answer 7

good

Answer 8

soo i got 1285.5683333 and i have to round to the nearest hundreth so the answer would be 1285.6?
