The formula for volume of a sphere is:
V = (4/3)(pi)(r3)
And since the radius(r) is half the length of the diameter we get:
r = 1/2 in
Plug in 1/2 for r and we get
V = (4/3)(pi)(1/2)3
V = (4/3)(pi)(1/8)
V = (1/6)(pi) in3
-or-
V = (pi/6) in3
-or-
V = 0.523598776 in3

The volume of the sphere is 38792.38 inches cubed Formula: Volume = PI x diameter cubed / 6 Step 1) 3.14 x 42 cubed / 6 = 38792.38609 Volume = 38792.38 inches cubed (the power of 3) +++ I have tested the above values but the standard formula for the volume of a sphere is 4/3.pi.(radius cubed).
Volume of sphere is 1/6 times pi times diameter cubed Thuis Volume = 1/6 (3.14) times diameter cubed or 0.5236 Diameter cubed
The volume of a cylinder is the product of the area of the base multiplied by the height. A washer is a portion of cylinder, and if the cylinder specified by the problem had no hole, its volume would be pi X (1/2)2 X 1/8 = pi/32 = about 0.09817 cubic inches. The volume of the actual washer is this value minus the volume of the hole, which is pi X (1/4)2 X 1/8 = pi/128 = about 0.024554 cubic inches. Therefore, the volume of the washer is about 0.09817 - 0.024554 = about 0.0736 cubic inches.
