Question

the radius of a car wheel is 18 cm how far would the wheel move after making 70 complete rotations . please mark it as the brainiest question

Answer 1

Answer:

7912cm

Step-by-step explanation:

Answer 2

Answer:

Distance covered by the  wheel after making 70 complete rotation is 7920 cm.

Step-by-step explanation:

Explanation:

Given, radius of car wheel = 18 cm

Circumference of wheel = $2\pi r$

First, we need to find the circumference of the car wheel.

Step 1:

so, circumference of the car wheel = $2\pi r$

Circumference = 2 × $\frac{22}{7}$ × 18 = $\frac{22 (18)(2)}{7}$ = $\frac{792}{7}$ cm

So,  $\frac{792}{7}$ cm is the distance the wheel covered  for one revolution.

Distance covered by the  wheel after making 70 complete rotation

= 70 ×$\frac{792}{7}$ = 7920 cm.

Final answer:

Hence, distance covered by the  wheel after making 70 complete rotation is 7920 cm.
