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 . 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.
The area of the shaded region is 1486 m².
The question requires you to find the area of the shaded part.Find the area of the triangle then subtract the area of the circle to remain with the area of the shaded region.
Area of a triangle = 1/2 *base length*height
Area of a triangle= 1/2*60*60=1800 m²
Area of the circle= πr²
Area of the circle=3.14*10*10=314 m²
Area of the shaded region = 1800-314=1486 m²
Area of of a triangle:
