Question

Calculate the circumference of a circle with
the followi radius:
0. 98cm
​

Answer 1

Answer:

Formula of Circumference of a circle = 2πr

| Value of π = 22/7 or 3.14 |

• If we take the value of π as 3.14, Then,

Given radius of circle = 0.98cm

= 2 × 3.14 × 0.98

= 6.28 × 0.98

= 6.1544cm Ans.

• If we take the value of π as 22/7, Then,

Given radius of the circle = 2πr

= 2 × 22/7 × 0.98

= 6.28 × 0.98

= 6.1544cm Ans.
