Question

What is the formula for the area of a circle?

(a) A = πd^2

(b) A = πs^2

(c) A = πr^2

(d) A = πa^2

I got this question during an online exam.

My question is from Perimeter and Area of a Circle topic in chapter Area Related to Circles of Mathematics – Class 10

Answer 1

Right answer is (c) A = πr^2

The best explanation: The area of a circle (A) = πr^2.

Where A is the area of the circle and r is the radius of the given circle.

The value of π is taken as \(\frac {22}{7}\).
