Question

7) How many times a wheel of radius 28 cm must rotate to cover a distance of 352 m?
(Take II=22/7)​

Answer 1

Answer:

200 times

Step-by-step explanation:

circumference of a circle =2llr

=2*22/7*0.28

=1.76m

a wheel rotates = 352

1.76

= 200 times

Answer 2

Circumference of a wheel

Radius of wheel= 28 cm

Circumference of wheel= 2(pie) r
= 2x22/7x28
= 176 cm
In meters= 176x1/100= 1.76 m
