Why is there no lateral surface area formula for a sphere?
A tennis ball has a radius of 3 cm. A soccer ball has a radius that is 5 times larger than the tennis ball. 1. How many times larger are the surface area and volume of the soccer ball? 2. Using the answer from #1, find the actual surface area and volume of the soccer ball.
