4/3*pi*radius3 = 523.6 Making the radius the subject of the above gives it a value of 5.000003897 or about 5 cm
The volume is proportiuo9nal to the cube of the radius, so doubling the radiuscauses the volume to increase to (2)3= 8 times its original value.
Volume of a sphere equals 4 thirds times pi times the radius cubed. The radius here is 2 meters because the radius is one half the diameter. So plugging in the radius yields an exact result of 32pi ----- cubic meters 3 Or an equally correct but less precise value of 33.5103 cubic meters.
Surface area: 4*pi*radius2 = 28 Making the radius the subject of the above gives it a value of 1.49270533 or about 1.5 inches
To find the volume of a sphere, you can use the formula V = (4/3)πr^3, where r is the radius of the sphere. Since the diameter is 16 inches, the radius would be half of that, which is 8 inches. Plugging this value into the formula, you get V = (4/3)π(8)^3 = (4/3)π(512) = 2144π cubic inches. So, the volume of the sphere is 2144π cubic inches.
