Answer:

The formula for the volume of a sphere is:

V = (4/3)πr³

We can rearrange this formula to solve for the radius (r):

r = [(3V) / (4π)]^(1/3)

where V is the volume of the sphere.

Substituting the given volume of the beach ball, we get:

r = [(3 × 10,332 in³) / (4 × 3.14)]^(1/3)

r = 10.27 in

Rounding to the nearest tenth, the approximate radius of the beach ball is 10.3 inches.

Answer:

Explanation:

Given diameter of a beach ball is d=10 inches.Let us find the radius of the beach ball:d=2 r10=2×rr=102∴r=5Therefore, the radius of a beach is 5 inches.Let us find the volume of air contained inside the beach ball:V=43 π×r3=43 π×53=43 π×125=500π3∴V=523.59877Therefore, the volume of air contained inside the beach ball is approximately 523.6 in3.
