A sphere has a volume of 36π in3. What is the radius of the sphere?

amm1812

Answer:

r = 3 inches

Step-by-step explanation:

The formula for the volume of a sphere is the following:

V = (4π/3)r^3

You know the volume so plug that in for V:

36π = (4π/3)r^3

27 = r^3 (multiply by 3/4π to get r^3 by itself)

r = 3 (you take the cube root of r and 27 to get the value of r)

Hope this helps :)

I would appreciate if you answered!

Answer:

None of those options

Step-by-step explanation:

I just did the work myself and even ran it through a calculator but the correct answer isn't one of those options. Here's my work:

$-\frac{5}{6} =z+\frac{1}{8}\\-\frac{5}{8}-\frac{1}{8}=z\\-\frac{40}{48}-\frac{6}{48}=z\\-\frac{46}{48}=z\\-\frac{23}{24}$

I'd contact you teacher about that...it might be an error in their system (it's happened to me a few times before where the correct answer is marked as incorrect or isn't even an option)
