Answer :
Answer:
value of pi
Step-by-step explanation:
area of circle = pi x r x r
d= 2 x r
r = 1
pi x 1 x 1 = pi
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
Radius is half of the diameter
So radius = 2/2 = 1
Then the area = pi * 1^2 = pi * 1 =pi
