What is the approximate circumference of a semicircle with a radius of 35 inches?
kakasveta [241]

If it were a complete circle, its circumference would be

             (π) x (diameter) = (π) x (2R)  =  70 π inches .

Since it's only half of the circle, the length of the curved part is

                              70 π / 2  = 35 π  =  <em>109.9 inches</em> .
