Answer 2

Given:

Find the area of the circle whose circumference is 154 cm.

Solution:

↪ Circumference of Circle= 2πr

↪ 154= 2 x 22/7 x Radius

↪ 77= 22/7 x Radius

↪ 77 x 7 = 22 x Radius

↪ 539 = 22 x Radius

↪539 ÷ 22 = Radius

↪ 24.5 = Radius

↪ It was given that diameter of the Circle= side of the square

↪ Diameter of Circle= 2 x Radius

↪ Diameter of o ↪ 49 x 49

↪ Area of Square= 2401cm²

Therefore, Area 2401cm²

Therefore, Area of Square= 2401cm²
