Find the Volume of a hemisphere with a diameter of 17 cm. Use pi = 3.14 and round to the nearest hundredth. can some one show me what i'mdoing wrong?

this is what i got:
4/3*3.15*17^3

you forgot to split the diameter in half to get the radius.
You used the diameter in the formula.

Also 4/3(pi)r^3 is the volume of the sphere. For the hemisphere you will need to half the volume.

so

4/6*3.14*8.5^3

1 answer

4/3*3.14*(8.5)^3
equals 2571.14
