Question

A radius of a wheel is 14cm.the distance covered by the wheel in making 2complete revolutions is

Answer 1

Answer:

radius- 14cm

circumference= 2πr

= 2*22/7*14

=88cm

distance covered for 2 revolutions = 2*88 = 176cm

Answer 2

Answer:

Total distance travelled by the wheel is 176 cm..

Step-by-step explanation:

Given,

Radius of the wheel is 14 cm.

We know, on practical basis, the distance travelled by a wheel to complete one rotation is equal to its circumference.

Here,

Total distance covered by the wheel :

= > 2 x distance covered in a revolution

= > 2 x circumference of the wheel

= > 2 x ( 2 x π x 14 cm ) { circumference of circle = 2π.radius , here, radius = 14 cm }

= > 4 x ( 22 / 7 ) x 14 cm { π = 22 / 7 , here }

= > 4 x 22 x 2 cm

= > 176 cm

Hence, the total distance travelled by the wheel is 176 cm.
