Question

Viru made 5 rounds around circular garden of radius 3.5m. How many kilometre he walked around the garden?

Answer 1

Answer:

2πr

2*22/7*3.5

22 m

viru made 5 rounds

total distance he walk

= 5*22

= 110 m

or, o11 km

Answer 2

Step-by-step explanation:

Radius of garden = 3.5 m

Therefore circumference of garden = 2πr

$2 \times \frac{22}{7} \times 3.5 \\ \frac{44}{7} \times \frac{35}{10} \\ 22 \: m$

so distance covered in 5 round = 22×5 = 110 m= 0.11 km
