Find the perimeter of a semicircle.if its diameter is 14cm?
Calculating the Perimeter of a Semicircle
Calculating the perimeter of a semicircle involves finding the distance around the curved edge of half a circle. Here's how you can calculate the perimeter of a semicircle with a given diameter of 14cm:
Step 1: Find the radius of the semicircle
- The diameter of the semicircle is given as 14cm.
- The radius of the semicircle is half of the diameter, so the radius = 14cm / 2 = 7cm.
Step 2: Calculate the perimeter of the semicircle
- The formula to find the perimeter of a semicircle is P = πr + 2r, where P is the perimeter and r is the radius.
- Substituting the values, P = π(7) + 2(7) = 7π + 14.
Step 3: Approximate the perimeter
- Use the approximate value of π as 3.14 to find the perimeter of the semicircle.
- P ≈ 7(3.14) + 14 = 21.98 + 14 = 35.98 cm.
Therefore, the perimeter of the semicircle with a diameter of 14cm is approximately 35.98 cm.
