| Given:
Vsh = Vp,
Vp = 48 cm ^ 3.
Find – R.
By determining the volume of the ball:
Vsh = 4/3 * n * R ^ 3.
From the formula for the volume of the sphere, we express the radius of the sphere:
4/3 * n * R ^ 3 = Vn;
4 * n * R ^ 3 = Vn * 3;
R ^ 3 = Vn * 3 / (4 * n);
R = ∛ (Vp * 3 / (4 * n)).
Substitute numerical values into the formula for the radius and find it:
R = ∛ (48 * 3 / (4 * 3)) = ∛12 = 2 (cm).
Answer: R = 2 cm.
