Question

a wheel of a car covers a distance of 3520 cm in 20 rotations. find the radius of the wheel​

Answer 1

Answer:

The radius of wheel is 28.025 units

Explanation:

Total distance covered 3520.

This distance is covered in 20 rotation.

SO distance covered in one rotation will be = 3520 / 20 = 176

Distance covered in one revolution is equal to the circumference of a circle

Hence

176 = 2 x pi x r

R = 176 / 2 x 3.14

R = 28.025

The radius of wheel is 28.025 units

Answer 2

Answer:

28cm

Step-by-step explanation:

20=3520/20

=176

2πr=176

=πr=88

r=88*7/22

r=28 cm
