Question

what is the perimeter of the region if a semicircle has a diameter of 10? You will get 100 points

Answer 1

Circumference of a circle= πd = 10π
Divide by 2 and then add 10

Final answer= 25.7

Answer 2

Answer: 5pi + 10

Step-by-step explanation:

the perimeter of a semicircle would be half the circumference of a circle plus the diameter

diameter = 10

circumference of circle = diameter * pi = 10 * pi = 10 pi

half a circumference of circle = 10 pi / 2 = 5pi

perimeter = 5pi + 10
