If the perimeter of a circle is 88 m, then what is the area of the circle? (π=227)(\pi={{22} \over 7})

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 616 m2.

Formula

The perimeter of the circle = 2πR

2πR = 88

2 * (22/7) * R = 88

R = 14 m

The area of the circle = πR2 = (22/7) * 14 * 14 = 616 m2
