The circumference of a circle is 132 cm. The area of circle is: (Take π=227\pi = {22\over7})

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 1386 cm2.

Circumference of circle = 2πr2 \pi r

Area of circle =πr2\pi r^2

According to the given question,

2πr2 \pi r = 132

⇒ 2 × 22/7 × r = 132

⇒ r = 21 cm

Now, area = (22/7) × 21 × 21

⇒ 22 × 63 = 1386 cm2
