Pqrs is a diameter of a circle of radius 6 cm .the lengths pq, qr, rs are equal. semicircles are drawn on pq and qs as diameters. find the perimeter of shaded region

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
