Volume = about 56.55 units3
A hemisphere with a radius of 3 has a volume of 56.55 units3
A hemisphere with a radius of 3 feet has a volume of 56.55 cubic feet.
The volume is 56.55m3
Volume of Hemisphere = 2/3 * Pi * (radius)^3 Volume of Cone = 1/3 * Pi * (radius)^2 * height where Pi = 22/7 (approx)
127.17
Volume of a hemisphere = 2/3*pi*radius3 Volume = 2094.395102 cubic units
V=(2/3)πr V= volume R=Radius
Vol = 2/3 * pi * r3 where r is the radius
Volume = (4/3*pi*103) divided by 2 = 2094.395 cubic units
Is 11ft the radius or diameter? If it is the radius then the volume = 1/2 [4/3 * pi * r^3] (where * means multiply and ^3 means to the power of three or cubed) So for a radius of 11ft, the Volume is 13,938.20 cu ft. If the diameter is 11ft, then the radius will be 5.5ft and the Volume is 348.45 cu ft
Density = mass/ volume volume= 4/3(pie)(r^3) ***r= radius in meters** so find volume then divide mass by volume and there you go.
Hemisphere volume = [(4 / 3) πr3] / 2
