Question

If the perimeter of a semi circle is 10.28 m what is the semi circles radius

Answer 1

Answer:

3.28 m

Step-by-step explanation:

Here's one easy way to do this problem:   Double the given 10.28 m to find the circumference of the entire circle:  It is 20.56,  Since C = 2(pi)(r), divide this result (20.56) by (2*pi) to determine the radius:

         C           29.56

r = ---------- =  ------------ = 3.28 m

        2π            6.28
