Question

what is the perimeter os a semi circle whose diameter is 6 feet long?

Answer 1

Perimeter of semi circle is c = pi*d

Here d = 6feet

c = 3.14*6

c = 18.84

Perimeter of semi circle = (18.84/2)+6

= 9.42+6

Perimeter of given semi circle is 15.42feet.

Your answer is correct.

Perimeter of circle  = pi*d

Perimeter of semi circle =( pi*d)/2 + d.
