Answer:
25/3 pi cm^2
26.18 cm^2
Explanation:
The area of a circle is
A = pi r^2
We are taking a sector that is 30 degrees. Since a circle is 360 degrees
The fractional part of the circle is 30/360
Multiply the fraction by the area to find the shaded area
sector area = 30/360 * pi (10)^2
=1/12 * pi *100
=25/3 * pi is the exact answer
or approximately 26.18 cm^2
