Question

What will be perimeter of the semi-circle if the radius of the circle is ¼ of a meter.​

Answer 1

Answer:

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.

Answer 2

As formula of perimeter of semicircle = πr + 2r

radius = 1/4 m

by solving,

= 3.14 x 1/4 + 2 x 1/4

=0.785 + 0.5

=1.285

it is your answer hope it helps
