Naya [18.7K]

Volume of sphere = 1766.25 cm^3

Step-by-step explanation:

The radius of sphere = 7.5 cm

Volume of sphere = ?

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

Putting values:

$Volume= \frac{4}{3}\pi r^3\\Volume=\frac{4}{3}*3.14* (7.5)^3\\Volume= 1766.25\,\,\,cm^3$

So, Volume of sphere = 1766.25 cm^3

I feel like I’m missing something simple. Please help explain?

5(12)=7.5 x

x = 5(12)/7.5 = 8
