Question

How do you find the area of a circle with the diameter of 2?

Answer 1

The formula of the area of a circle = pi * (radius)^2
Radius is half of the diameter
So radius = 2/2 = 1
Then the area = pi * 1^2 = pi * 1 =pi

Answer 2

value of pi

Explanation:

area of circle = pi x r x r

d= 2 x r

r = 1

pi x 1 x 1 = pi
