Question

a wire of length 36 cm is bent in the form of a semicircle what is the radius of semicircle6

Answer 1

The length of the wire is 36 cm. So, the circumference is 36 cm of the semicircle. So pie * radius = 36
radius = 11.45cm

Answer 2

Answer:

Length of wire is in the form of semicircle.

Given, length of wire =36cm

Perimeter of the semicircle = 36cm

According to question

πr+2r=36

r(π+2)=36

r(22/7+2)=36

r(36/7)=36

r=36÷36/7

r=36×7/36

r=7cm
