The formula for the volume of a sphere is 1/6 x pi x d^3, so for a hemisphere it would be just half of this, or 1/12 x pi x d^3. I'm sure you can take it from there. (1/12 is 0.08333...)

Well a hemisphere is one half of a sphere so...
the equation for the volume of a sphere is:
(4/3)*pi*r^3
r is for radius which is 1/2 the diameter so
using your data
(4/3)*3.14*(17/2)^3=2571.137 cm^3
divide that by two to get the hemisphere and you have:
2571.137/2=1285.569 cm^3

V=2*(r^3*pi)/3
r=17/2cm
pi=3.14
V=2*(17/2)^3*3.14/3~=1285cm^3
?

Volume of a sphere is (4/3)Ïr³
hemisphere would be half that.
The radius in this case is 8.5cm.
so.. (4/6)Ï8.5³ =
(4/6)*3.14*614.125 =
1285.56833...
Nearest hundredth is
1285.57

V= 4 X pie X radius cubed divided by 6(cuz its half of a sphere)
V= 4 X 3.14 X 8.5 cubed divided by 6
V= 1285.57 cm cubed

V = ((Pi/6)d^3)/2
V = ((3.14/6) * 17^3)/2
V = about 1285.57cm^3

V = [ (4/3 ).Ï.r³ ] / 2
V = (2/3) x Ï x 8.5³ cm³
V = 1285.57 cm³

volume of a hemisphere=2/3pi(r)cubed
2/3(3.14)(8.5)(8.5)(8.5)=1285.57
