Question

Given a spherical weather balloon with a volume of 36π cubic feet. What is the diameter, in feet, of the weather balloon?

A) 3
B) 6
C) 9
D) 12

Answer 1

b)6

Explanation:

Answer 2

option B
`D=6\ ft`

Explanation:

we know that

The volume of the sphere is equal to

`V=(4)/(3)\pi r^(3)`

In this problem we have

`V=36\pi\ ft^(3)`

substitute and solve for r

`36\pi=(4)/(3)\pi r^(3)`

simplify

`27=r^(3)`

`r=3\ ft`

Find the diameter

`D=2r=2(3)=6\ ft`
