Question

Answer it with explanation

Answer 1

hey mate.

Distance = no of revolutions × circumference of a wheel

=) 176m = n × 22/7 × 40cm

=) 176 × 100 × 7 / 22*40 = n

=) 140 = n

Answer 2

Answer:

Option(A)

Step-by-step explanation:

Given, diameter = 40 cm.

Given, distance = 176 m = 17600 cm.

Circumference of wheel =  πd =

= (22/7) * 40

= 880/7 cm.

So,the distance covered in 1 revolution = 880/7 cm.

Therefore, total number of revolutions:

= 176m/πd

= (176 * 7 * 100)/880

= 140

                                                                =
