Question
A ball has a radius of 8 cm. Find the circumference of the ball. (This is the amount of string that would be required to encircle the ball exactly once.)Round your answer to the nearest tenth. Do not type the units in the space below.
Solution
The formula to find the circumference of a circle (or in this case, a ball) is C = 2πr, where r is the radius of the circle.
Step 1: Identify the radius of the ball. In this case, the radius (r) is given as 8 cm.
Step 2: Substitute the radius into the formula. So, C = 2π(8).
Step 3: Calculate the circumference. C = 2 * 3.14 * 8 = 50.24 cm.
Step 4: Round your answer to the nearest tenth. So, the circumference of the ball is approximately 50.2 cm.
