If a regulation NBA basketball has a circumference of 295 in

If a regulation NBA basketball has a circumference of 29.5 inches, then find the following: diameter = _____ radius = _____ Surface Area = _____ Volume = _____ A hemispherical dome holds a volume of 486pi ft^3. Find the surface area (omit the area of the circle).

Solution

Please post 1 question per post:

circumference = 2*pi*r = 29.5

r = 4.697

Diameter = 2*4.697 = 9.394

Surface area = 4*pi*r^2 = 4*3.14*(4.697^2) = 277.093

Volume = (4/3)*pi*(4.697)^3

= 433.84 in^3
