Question

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

Answer 1

Answer:

option B $D=6\ ft$

Step-by-step explanation:

we know that

The volume of the sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

In this problem we have

$V=36\pi\ ft^{3}$

substitute and solve for r

$36\pi=\frac{4}{3}\pi r^{3}$

simplify

$27=r^{3}$

$r=3\ ft$

Find the diameter

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

Answer 2

Answer:

b)6
