Answer:
The area of the circle
Explanation:
The area of a circle is given by:
A = pi•r^2
☝️That is "Area equals pi times r squared"
Fun fact: you can use r (radius) or d (diameter) to find the circumference (distance all the way around a circle)
C = pi • d
or C = 2pi • r
But for area (all the space inside)
A = pi • r^2
