Question
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 = 64π Triangle area = 36π Total area of the circular ground = Sum of both areas Find Total Area 64π+36π=100π Find Radius of Circular Ground Let radius = R, πR2 =100π Cancel π: R2 =100⇒ R=10 Diameter=2R=2×10=20
