A circle's area can be found using the equation π*r^2 (radius squared) and the circumference of a circle is 2πr.
In order to find the area, then, we need to find the radius first:
We will use 3.14 as the value of pi to keep the math a little more simple.
2πr=18.84 (given from the initial question)
πr=9.42
r=3
Then, we plug that back into the area equation:
π(r^2)=
π(3^2)=
π*9=28.26

How do you calculate circumference and area of pi?
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius

What is the area of a circle in terms of its circumference?
Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.
