What is area of circle?
The area of a circle measurement of a circle which is calculated as π[tex]r^{2}[/tex].
How to find the degree measure of an arc?
The degree measure can be calculated as under:
20*π/360=4*π/x solve for xx
=360*4*π/(20*π)
=1440/20
=72 degrees.
Hence the degree measure of an arc 4 (π) having radius 10 ft. is 72°.
