8. If the volume of a sphere is 24 π, what is the radius?
Sergeu [11.5K]

Answer:

r=0.179 or r =\sqrt[3]{5.7296}

Step-by-step explanation:

Hello!

The volume of a sphere equation is:

V = 4π/3 r³

The question asking, what is the radius that has a volume of 24pi. We should now rearrange the volume of a sphere equation to isolate r.

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

\frac{1}{V} = \frac{3r^{3} }{4\pi }  

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

r = \sqrt[3]{\frac{3V}{4\pi } }

r = \sqrt[3]{\frac{3*24}{4\pi } }

r = about 1.79

Hope this helps!
