Question

If the diametar of a ssemicircular protactoe is 14 cm , then its perimeter is​

Answer 1

Answer:

35.99

Step-by-step explanation:

A protractor is a semicircle. Let the radius be R. Then it's perimeter = $\pi R + 2R$.

Since diameter is 14 cm, radius is 7cm.

So, perimeter = $7\pi + 14 = 35.99$

Answer 2

Step-by-step explanation:

Given ,

Diameter = 14 cm

Perimeter of semicircle =

$\pi \times d \ \times \frac{1}{2}$

$\frac{22}{7} \times 14 \times \frac{1}{2}$

=22

Therefore , Perimeter of semicircle is 22
