What is the best approximation for the perimeter of a semicircle with a diameter of 35 inches?

use 3.14 to approximate pi.

89.95 inches.

Step-by-step explanation:

We are asked to find the best approximation for the perimeter of a semicircle whose diameter is 35 inches.

, where D represents diameter of semicircle.

Upon substituting D=35 and in above formula we will get,

Therefore, perimeter of our given semicircle is 89.95 inches.

54.95 inches.

Step-by-step explanation:

Perimeter of a circle = 2πr

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

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.
