A sphere with 20 cubic feet of volume has the following:A radius of 1.684 feetA diameter of 3.368 feetA circumference of 10.58 feetA surface area of 35.63 square feet
The surface area is 3,267.2 units2
A sphere with a radius of 20 units has a volume of 33,510.32 cubic units.
376.8
The surface area is equal to the (circumference of the base) times (the length). Circumference of the base = (2 pi) times (radius) = 16 pi Surface area = (16 pi) times 20 = 320 pi = 1,005.310 square units (rounded to 3 decimal places)
Surface area = 20*pi square units
The great circle has circumference 40pi and we know circumference is 2pixr so 20 is the radius of the sphere. Now use this and the formula that surface area is 4pir^2 so the surface are is 4pi(20)^2. or pi(1600)

h = 57.19
You need to know the radius/diameter or the height of the drum.
SA = 1,187.5 units2

The surface area is equal to the (circumference of the base) times (the length). Circumference of the base = (2 pi) times (radius) = 16 pi Surface area = (16 pi) times 20 = 320 pi = 1,005.310 square units (rounded to 3 decimal places)
Volume of the sphere: 4/3*pi*20^3 = 33510 cubic units rounded
