radius = circumference /(2×pi) =26×pi / (2×pi) = 13
Your answer is 3/5, the picture below shows how sin cos tan work!
The area of a circle is pi * r^2
The radius of the circle is 6
So the area of the full circle is pi*36
1/4 of the circle is cut off so we have to take a fourth off the area.
36pi * 3 / 4 = 27pi
Or 84.823 cm^2
