Answer:
formula is πr² ( pi x radius squared)
Explanation:
the value of π is 3.142...
multiply this value with the squared radius of the circle and you'll get your answer.
For example:
we have a circle with diameter 5
so, π x 5² = 3.142 x 25 = 78.5
Read Exp:
Area = 3.14 x r^2
I've Included a picture to tell you how to get the diameter as well as the circumference.
