What is the length of diameter of a circular ground
whose area is equal to the sum of the area of a circle of radius 8 m and a triangle of area 36 πm² ?Solution
ATQ, Given: Circle with radius = 8 m → Area = 64Ï€ Triangle area = 36Ï€ Total area of the circular ground = Sum of both areas Find Total Area 64Ï€+36Ï€=100Ï€ Find Radius of Circular Ground Let radius = R, Ï€R2 =100Ï€ Cancel Ï€: R2 =100⇒ R=10 Diameter=2R=2×10=20Â
