Question

2. Using 3.14 as a value of n, find the approximate volume of each sphere below. Round to

the nearest cubic inch.
a)
4 in
Like
example 1
b)
12 in

Answer 1

a: 268
`in^(3)`

b: 904
`in^(3)`

Explanation:

Volume of a sphere:
`(4)/(3) \pi r^3`

a:
`(4)/(3) (3.14)(4)^3` = 267.95

b: r = 12/2 = 6

`(4)/(3) (3.14)(6)^3` = 904.32
