Question

Find the circumference of a circle whose area is 301.84 cm².

Answer 1

Answer:

Circumference of a circle is 61.6 cm.

Step-by-step explanation:

SOLUTION :  

Given :

Area of circle = 301.84 cm²

Area of circle = πr²

301.84 = πr²

301.84 = 22/7 × r²

r² = (301.84 × 7)/22

r² = 96.24

r = √96.24

r = 9.81 cm

Circumference of the circle,C = 2πr

C = 2 × 22/7 × 9.81

C = (44 × 9.81)/7

C = 431.64/7

C = 61.6 cm

Hence, circumference of a circle is 61.6 cm.
