Question

attempted and in all other cases.
If the circumference of a circle
is 132 cm. then its radius is
(A) 21 cm
(B) 42 cm
C) 14 cm
(D) 28 cm​

Answer 1

Answer:

(a)21cm

Step-by-step explanation:

circumference = 2 pi r

132 = 2 X 22/7 X r

r = 132 X 7 / 44

r = 924 / 44

r = 21

therefore option (a)21cm is the correct answer

hope this answered your question :)

Answer 2

As we know circumference of circle =2πr

We have given that circumference of circle is 132cm.

So,

2πr=132

≈ 2×22/7×r=132

≈ r=132×7/44

≈ r= 21 cm

Hence the correct option ✔️is (A) 21 CM.
