Question

5. The diameter of a cycle's wheel is 28 cm. Find how many times the wheel will revolve in
order to cover a distance of 704 m.​

Answer 1

Answer:

Given :-

Diameter of wheel = 28 cm

Distance = 704 m

To Find :-

How many times it revolves

SoluTion :-

Radius = Diameter/2

Radius = 28/2

Radius = 14 cm

Circumference of circle = 2πr

Circumference = 2×22/7×14

Circumference = 2 × 22 × 2

Circumference = 4 × 22

Circumference = 88 cm

Now,

Converting m - cm

1 m = 100 cm

704 m = 704 × 100 = 70400 cm²

Total times = 70400/88

Total time it cover = 800
