Question

e. A person walks in a semicircular path of diameter 700 m Find this
by him. If he starts walk from A and returns to A but he goes through B
returns through BOA​

Answer 1

Given that,

• Diameter of the semi circular path = 700 m
• Distance covered by the person = ?

we know that,

• Distance covered by the person = circumference of the semi circle
• Radius of the semi circle = D/2 = 700 m / 2 = 350 m

• Distance = 2πr/2
• Distance = πr
• Distance = 22/7 × 350 m
• Distance = 1100 m.

Therefore, the distance covered by the person is 1100 meters.
