1.	A 64 cm wide path is made around a circular garden having a diameter of 10 metres. The area (in m2) of the path is closest to: (Take \(\pi = \frac{{22}}{7}\))1. 212. 153. 94. 10
Answer» Correct Answer - Option 1 : 21 Given: Length of circular path = 64cm Diameter of Circular garden = 10m = 1000 cm Radius of Circular garden = 10/2 m = 500 cm Quantity I: Inner radius = 500 cm Outer radius = 564 cm Area of path = Outer area - Inner area ⇒ 22/7 × (5642 - 5002) ⇒ 22/7 × (564 + 500)(564 - 500) ⇒ 22/7 × (1064)(64) ⇒ 21.4016 m2 ⇒ 21 m2(approx.)

A 64 cm wide path is made around a circular garden having a diameter of 10 metres. The area (in m2) of the path is closest to: (Take \(\pi = \frac{{22}}{7}\))1. 212. 153. 94. 10

Answer» Correct Answer - Option 1 : 21

Given:

Length of circular path = 64cm

Diameter of Circular garden = 10m = 1000 cm

Radius of Circular garden = 10/2 m = 500 cm

Quantity I:

Inner radius = 500 cm

Outer radius = 564 cm

Area of path = Outer area - Inner area

⇒ 22/7 × (5642 - 5002)

⇒ 22/7 × (564 + 500)(564 - 500)

⇒ 22/7 × (1064)(64)

⇒ 21.4016 m2

⇒ 21 m2(approx.)
