Question

find the distance covered by the wheel of a bus is a2500 ratio if the diameter of wheel is 98 CM

Answer 1

Given :

Diameter of the wheel = 98 cm

To Find :

Distance covered by the wheel in 2500 Revolutions.

Solution :

Circumference of the circle = 2πr = 2rπ = dπ = 98× 22/7 = 308 cm.

Now,

Distance covered in 1 Revolution = 308 cm

Distance covered in 2500 Revolutions = 308× 2500 = 7,70,000 cm .

Answer 2

$\bf{Here \: is \: the \: answer}$

Given => Diameter of the wheel = 98 cm.

Total revolutions of wheel => 2500

Distance covered by wheel = ?

We know that ,

Circumference = 2 π r

Also,
d = 2r

Therefore,
We can also write as,

Circumference = π d

= 22/7 × 98

= 22 × 14

= 308

Circumference = 308 cm

Now,

For 2500 revolutions ,

Total Distance = 2500 × 308
= 7,70,000

Therefore,
Total Distance travelled = 7,70,000 cm.
