Question

If the area of a circle is 196π m2 then the circumference of the circle is _______

• A. 88 m
• B. 76 m
• C. 44 m
• D. 58 m

Answer 1

Answer:

A. 88 m

Solution:

Given:

Area of a circle = 196π

Formula used:

Area of a circle =πr²

Circumference  = 2πr

Calculation:

⇒ Area of a circle =πr²

196π=πr²

r= 14 m

Circumference = 2πr $=2\times{\frac{22}{7}}\times{14}=88m$

⇒ Hence, The perimeter of a circle is 88 m
