Here are the solutions to the problems.

5. A sphere, a cone and a cylinder have equal radii. Their curved surface areas are equal. If the volume of the sphere is $1437 \text{ cm}^3$. (Give answers to 4 significant figures)

a) Find the radius of the sphere.

Step 1: The formula for the volume of a sphere is $V_s = \frac{4}{3}\pi r^3$.
We are given $V_s = 1437 \text{ cm}^3$.

$$1437 = \frac{4}{3}\pi r^3$$

Step 2: Solve for $r^3$.
