Question

Find the number of sides of a rem
polygon if each of its interior angle
37
Two circles, each of radius 7 CM
intersect each other. The distance
between their centres is 72 cm. Find
the area common to both the circles.​

Answer 1

Answer:

The combined area of both sectors including the intersection area is (1/8) of each circle, since the arc is 45 degrees. That makes it 49*pi/8 *2 or 49*pi/4 cm^2 for the combined area. Numerically, this is 38.48 cm^2, whereas the area of the whole triangle, which has overlap, is 24.5 cm^2.
