Find the area of the shaded region in the figure below, if the radius of the outer circle is 6 and the radius of the inner ci

math algebra

Answer 1

Answer #1

Area of shaded region is given by subtracting area of small circle from area of big circle .

shaded area= are of big circle- area of small circle

area of circle = ar?

small circle radius is 2 . so area is

area of small circle = 7 * 22 = 47

Big circle radius is 6 .so area is

area of big circle = 7 *62 = 367

so area of shaded region

so answer is
