To calculate the perimeter of a semicircle, you need to find the circumference of the corresponding full circle and divide it by 2. The formula to calculate the circumference of a circle is:
C = 2πr
where C is the circumference and r is the radius. Given a radius of 10 meters, we can calculate the perimeter of the semicircle as follows:
C = 2π(10)
= 20π
To find the perimeter of the semicircle, we divide this circumference by 2:
Perimeter = C/2
= (20π)/2
= 10π
Therefore, the perimeter of the semicircle with a radius of 10 meters is 10π meters (or approximately 31.42 meters).
