Find the Area circle (1)
r=1r=1
Step 1
The area of a circle is equal to Pi ππ times the radius rr squared.
π(radius)2π(radius)2
Step 2
Substitute in the value of the radius r=1r=1 into the formula for the area of a circle. Pi ππ is approximately equal to 3.143.14.
π12π12
Step 3
One to any power is one.
