Question

A wire of length is 132 cm is bend to form a circle. Find the perimeter, radius and diameter of the formed circle.

Answer 1

Answer:

Perimeter=circumference=132

C=2πr

Hence

2πr=132

r=132/2π=132×7/(2×22) ==21

d=2r=2×21=42

Perimeter=132cm

Radius=21cm

Diameter=42cm

Answer 2

Step-by-step explanation:

The wire of length = perimater of circle

So, perimeter of circle =132 cm

>2πr = 132

> 2×22/7×r = 132

> r = 132×7

––––

2×22

>r = 3×7

>r= 21cm

Diameter of the circle =2r

= 2×21

= 42 cm
