Question

if a wheel has radius 4cm then distance covered by it in 700revolutions is

Answer 1

first find out the circumference because to find out the distance traveled we have to first find out the total area covered through circumference
C=2*pie*r
= 2 * 22/7 * 4
= 25.136

So the circumference is 25.136 and it can revolve 700 times that means
25.136*700
17595.2 km

Answer 2

Radius of wheel=4
Circumference of circle=2pi r
=2×22/7×4=176/7 cm
700 revolution = 700 × 176/7 =17600cm
hence the distance covered=176 m
