Answer:
54.95 inches.
Step-by-step explanation:
Perimeter of a circle = 2πr
<h3>So, perimeter of a semicircle = πr/2 = πr</h3>
where π = 3.14 and r is the radius of semicircle.
Given that,
diameter of semicircle = 35 inches
radius of semicircle will be half of its diameter = 35/2 = 17.5 inches
<h2>Solution</h2>
Perimeter of a semicircle = πr
= 3.14 (17.5)
= 54.95 inches
So, the best approximation for the perimeter of a semicircle with a diameter of 35 inches is 54.95 inches.
