Question

A basketball has a circumference of 29.5 inches using 3.14 as an approximation for pie what is the basketball volume to the nearest cubic inch

Answer 1

`(2\pi)(r) = 29.5`

`r = (29.5)/(2\pi)`

`v = (4)/(3) \pi {( (29.5)/(2\pi) )}^(3) = 434 \: {inches}^(3)`

`v = (4)/(3) (3.14) ({ (29.5)/(2(3.14)) })^(3) = 434 \: {inches}^(3)`
