Question

The circumference of a circular Garden is 484 a 1.75 metres Wide Road runs around the garden find the area of the road

Answer 1

Answer:

CIRCUMFERENCE OF CIRCLE = 2ΠR = 484

R = 484 / (2Π )

R = (484 × 7) / 22× 2

R = 44 m

Area = ΠR^2 = Π×44^2= 6084.57 m^2

AREA INCLUDING WIDE ROAD = ΠR^2= Π×55.75^2

= 6578.19 m^2

AREA OF THE WIDE ROAD = 6578.19-6084.57

= 493.61 m^2
