Volume of the sphere: 4/3*pi*9^3 = 972*pi cubic units
The volume of a cylinder can be expressed asV = (pi)r2hwhere V is the volume, r is the radius, and h is the height. (The variables stuck together mean to multiply)If the diameter of the cylinder is 24 in, then the radius is half of that, or 12 in.And the height (length) is 36 in.V = (pi)r2hV = (pi)(12)2(36)V = (pi)(144)(36)So now, the volume is officially 5,184 times pi, but if you want to approximate, it would be16,286.016 in3

Calculate the area of one circular face of the cylinder [pi (r2)], then multiply by the height of the cylinder. The answer will be approximate as pi is neither a terminating or repeating decimal. V=volume r=radius h=height V=[pi(r2)] h = [pi(32)] 3 =[pi (9)] 3 =(28.274) 3 =84.82 cm3 So, the volume of a cylinder with a radius and height of 3 cm will be approximately 84.82 cm3.
In a circle the area is A=pi*r2 so: A=pi*72 = pi*49 = 153.9380 So, an approximate value would be 153.94 square units
Volume of the sphere: 4/3*pi*9^3 = 972*pi cubic units
Volume = 4/3*pi*r3 = 5575.3 cubic inches
Volume = pi*252*25 = 49087.38521 or about 50,000 cubic feet
Volume = 4/3*pi*143 = about 11494 cubic inches
Volume of sphere = 4/3*pi*2.13 = 38.79238609 or about 39 cubic m
First find the radius: 4*pi*r2 = 100*pi cm2 Divide both sides by 4*pi and then square root the answer: radius = 5 cm Volume = 4/3*pi*radius3 Volume = 523.5987756 or about 524 cm3
radius = 6.19838715 volume = 4/3*pi*6.198387153 = 997.5271053 or about 998 cubic units
Divide the diameter by 2 to get the radius. Then use the formula: volume = (4/3) x pi x radius3

pi x radius x height = volume
It is about: 4/3*pi*2^3 = 33.5 cubic feet
If pi=3.14, then the circumference is ( 3.14 times the diameter).
