## anonymous one year ago What is the volume of a sphere with a radius of 6 inches? 112π cubic inches 288π cubic inches 290π cubic inches 300π cubic inches

1. jim_thompson5910

Volume of a Sphere $\Large V = \frac{4}{3}\pi*r^3$ plug in r = 6 and simplify

@jim_thompson5910 i got a answer i just wanna make sure other people get the same outcome i did.

3. jim_thompson5910

what is $\Large \frac{4}{3}*r^3$ equal to when r = 6

4. anonymous

i got 216 @jim_thompson5910

5. jim_thompson5910

close, but incorrect

6. Zale101

r^3=216 but you didn't finish solving the equation.

7. Zale101

6^3=216

$288 \pi$

$V_\text{sphere}(r)=\tfrac43\pi r^3$ $V_\text{sphere}(6\,[\text{in}])\\ =\tfrac43\pi(6\,[\text{in}])^3\\ =\tfrac43\pi\cdot 216\,[\text{in}]^3\\ =(\tfrac43\times216) \pi\,[\text{in}]^3\\=$
