Question

Find the diameter of a wheel whcih covers a distance of 286 m by 91 revolusion

Answer 1

Answer:

Step-by-step explanation:

Distance = no of revolution * circumference

286= 91 * 2*pi*r

286/91*2= pi r

1.57=3.14 * r

1.57/3.14 = r

0.5 =r

Diameter =1m

Answer 2

Answer:

Step-by-step explanation:

distance covered in one revolution = 286/91  = circumference of circle

286/91 = 2πr

r= 0.5m

diameter = 1 m
