The volume of a basketball is approximately 448.9 in³. Find the radius to the nearest tenth. Use the formula for the volume of a sphere.

A. 4.8 inches
B. 5.7 inches
C. 6.2 inches
D. 7.1 inches

Answer :

Final answer:

The radius of the basketball is approximately 5.7 inches.

Explanation:

To find the radius of the basketball, we need to use the formula for the volume of a sphere. The formula is:

V = (4/3)πr³

We know that the volume of the basketball is approximately 448.9 in³, so we can set up the equation:

448.9 = (4/3)πr³

To solve for r, we need to isolate it on one side of the equation. First, divide both sides of the equation by (4/3)π:

r³ = 448.9 / ((4/3)π)

Next, take the cube root of both sides:

r = (448.9 / ((4/3)π))^(1/3)

Using a calculator, we find that r is approximately 5.7 inches (rounded to the nearest tenth).
