Question

The circumference of a circle is given by the formula C =2πr where r is the measure of the radius?

Answer 1

Answer: 24

Explanation:

The perimeter of the length of the rectangle is 24. The perimeter or circumference of the circle can be found using the equation C=2π(r), where r= the radius of the circle. Since we have two semi-circles we can find the circumference of one whole circle with a radius of 4, which would be 8π.
