Question

what is the difference between radius and circumference of a semicircle if the area of semicircle is 88 CM square.​

Answer 1

Area = 22/7*1/2 *r²=88

         r²=88*2*7/22

         r²=56

         r=2√14cm

Circumference= 22/7*2√14

                        =44√14/7

 Difference = 44√14/7-2/14

                    = 44√14-14√14/7

                     = 30√14/7

Answer 2

Mathematically the difference between Radius and the circumference of a circle is 2π

But the actual difference is that the radius is the distance between the center and any point on the circle

and the perimeter of the semicircle is 44/7√14 + 4√14
