Example of Calculating Perimeter of Semicircle

Question: Find perimeter of a semicircle of radius 24 cm?


Given that,

Radius of semicircle (r) = 24 cm

Perimeter of a Semicircle = (π + 2) * r

Put the radius value in the formula.

Perimeter = (π + 2) * 24

Substitute constant π value in the above equation

Perimeter = (3.14 + 2) * 24

= 5.14 * 24

= 123.36

∴ Semicircle perimeter of radius 24 cm is 123.36 cm.

Frequently Asked Questions on Semicircle Perimeter

1. How do you define perimeter of a semicircle?

Semicircle is formed when a line passing through the center and that joins two ends on a circle. Perimeter of a semicircle is the sum of the half of the circumference of circle and its diameter. As we know that, perimeter of circle is 2πr or πd. So, perimeter of a semicircle is 1/2 (πd) +d or πr +2r. Formula is

Perimeter of a Semicircle = d (1/2 π + 1) or r (π + 1)

Where, r is the radius and d is the diameter.

2. What is the perimeter of a semicircle with a diameter of 12 cm?

Given diameter of semicircle = 12 cm

Semicircle Perimeter = 1/2 (πd) +d

= 1/2 (π * 12) + 12

= 6 * π + 12

= 6 * 3.14 + 12

= 18.84 + 12 = 30.84

Perimeter = 30.84
