Question

What is the best approximation for the perimeter of a semicircle with a diameter of 12 cm? use 3. 14 to approximate pi.

Answer 1

30.84

Explanation:

in order to find the perimeter you multiply 2 by pi (3.14) then multiply that answer by the radius which is 6. Then divide that answer by 2 since the shape is a semi circle then add the diameter (12) to that answer and you get 30.84.

2 * 3.14 * 6 / 2 + 12 = 30.84

Answer 2

Perimeter

Explanation:

perimeter is the sum of the whole sides of a figure
