Question

Find the distance covered by a wheel of radius 2.5 m, if it makes 230 revolutions.​

Answer 1

Answer:

Given:

Radius (r) = 2.5 m

No. of revolutions = 230

Step-by-step explanation:

Now since the wheel is making revolutions, it is rotating upon its circumference.

Therefore, we need to consider the circumference of the wheel.

Circumference = 2πr

putting in the value of r,

Circumference = 2*π*2.5

= 5π

Now, we all know π = 22/7

Now, distance covered in one revolution = 5π

distance cover in one revolution = 2πr

= 2×π×2.5

= 5π

so in 230 round = 230 × 5π

= 1150π meter

= 3612.8 meter
