Find the approximate area of the shaded region below, consisting of a right triangle with a circle cut out of it. Use 3.14 as an
approximation for pi.
An image shows a right triangle with a circle cut out of it. The legs that make up the right triangle are both 60 meters. The diameter of the circle cut out is 20 meters. All of the triangle is shaded, except where the circle is cut out.
A.544 square meters
B.1,486 square meters
C.3,286 square meters
D.314 square meters

we have
----> inequality 1
The solution of the inequality 1 is the shaded area below the solid red line
The solution is the region D and region C
-----> inequality 2
The solution of the inequality 2 is the shaded area above the solid blue line
The solution is the region B and region C
The solution of the system is the common area
so
The solution is the region C
see the attached figure
therefore
the answer is the option C
Region C
