The diameter of a semicircle is 15.2 centimeters. What is the semicircle's perimeter?Use 𝜋 ≈ 3.14 and round your answer to the nearest hundredth.
Question
Solution 1
To find the perimeter of a semicircle, you need to add the length of the half-circle (which is half the circumference of a full circle) and the diameter.
Step 1: Find the radius of the semicircle. The radius is half the diameter, so the radius is 15.2 cm / 2 = 7.6 cm.
Step 2: Find the circumferenc Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
