How do you find the shaded area of a circle
WebArea of shaded region = Area of large circle - Area of small circle = ∏R2 - ∏r2 = ∏ (25- (5/2)2) = ∏ (25- (25/4)) = (22/7)(75/4) Area of shaded region = 58.92 m2 b) Sum of the perimeters of the two circles = Perimeter of large circle + Perimeter of small circle = 2∏R+ 2∏r = 2 ∏ (R+r) = 2 (22/7)(5+5/2) = (22/7) (15) = 47.14 m WebThe solution is simple, if you consider that the perimeter of the shaded region is simply the sum of the arc length and the chord length. The arc length = Total Perimeter * (74/360) = 2*pi*8*74/360 = 10.332 m. The chord length = 2*r*sin (Angle/360) = 16*sin (74*pi/360) The sum of these two lengths is the perimeter of the shaded area.

WebSo if we take the principal root of 36, we get r is equal to 6. From there, we can use this to figure out the circumference. So the circumference is equal to 2 pi r. Circumference is equal to 2 pi r. And in this case, r is equal to 6. So it's equal to …
WebFeb 3, 2024 · Top Answerer. Divide the volume by the length to get the cross-sectional area. Assuming this is a regular hexagon, use the area formula to solve for the width of a side: A = (0.385) (s²). Multiply the side width thus calculated by the length of the prism. That gives you the area of one side. WebLet ‘r’ be the radius of smaller circle. Now, for first figure. Area of smaller circle (a)= π r². Area of bigger circle (A)= π R².
