Question

7) The diameter of circular garden is 49 m. Find the distance

covered by a runner if he makes 2 rounds round the

garden.

Answer 1

Circumference of the garden = 2pie r
= 2×22/7×24.5
= 154 m
Runner makes two round = 2×154
= 308 m
Runner covered 308 m

Answer 2

Answer:

308 m

Step-by-step explanation:

Find the radius:

Radius = Diameter ÷ 2

Radius = 49 ÷ 2 = 24.5 m

Find the distance covered in 1 round:

1 round = 2πr

1 round = 2π(24.5) = 154 m

Find the distance covered in 2 rounds:

1 round = 154 m

2 rounds = 154 x 2 = 308 m

Answer: 308 m
