Question

.If the circumference of the circle is 132m .Then calculate radius and diameter.​

Answer 1

Answer:

circunference =

$2\pi \: r$

132 =2 ×3.14 x r

r= 66 / 3.14 nearly equal to 3

r = 22 cm

d = 44 cm

Answer 2

Answer:

Radius - Formula - 132 = 2 Pi r(Radius)

= 2 X 22/7 X r = 132

= r= 21cm

Therefore Radius is 21 cm.

circumference= 2×(22/7)×r

132=44r/7

132×7/44=r

21 cm=r

d=2r

2×21 cm= d

=42 cm

Therefore diameter = 42 cm

Hope it helps!!!
