What is the radius of a sphere with a volume of 7961 cm", to the nearest tenth of a<br> centimeter?

statuscvo [17]

Answer:

12.4 cm

Step-by-step explanation:

Use the sphere volume formula, V = $\frac{4}{3}$ $\pi$ r³

Plug in the volume and solve for r, the radius:

V = $\frac{4}{3}$ $\pi$ r³

7961 = $\frac{4}{3}$ $\pi$ r³

1900.55 = r³

12.39 = r

So, the radius of the sphere is approximately 12.4 cm
