Question

The distance covered by a wheel of diameter 56 cm in one
revolution is :
(a) 156 cm
(b) 163 cm
(c) 168 cm
(d) 176 cm​
plz give answer by complete explanation

Answer 1

$\sf\large\red{\underline{\underline{Question:}}}$

• The distance covered by a wheel of diameter 56 cm in one
• revolution.

$\sf\large\red{\underline{\underline{Solution:}}}$

Distance covered by wheel in one revolution will be equally to its perimeter /circumference .

We know that,

$\red\bigstar\boxed{\bf Circumference_{\green{Circle}} =\sf 2\pi r \:\:\: Or\:\:\: \pi d}$

Distance covered = π × 56

Distance covered = $\dfrac{22}{7}\times 56$

Distance covered = 22 × 8

Distance covered = 176 cm

$\sf\large\red{\underline{\underline{Therefore,}}}$

• The distance covered by the wheel of 56 diameter in one revolution is 176 cm.

Answer 2

Given: The distance covered by a wheel of diameter 56 cm

To find: one revolution

Solution:

The formula for circumference= 2 pie r

Radius = circumference/2 = 56/2= 28cm

To find the distance covered by a wheel of diameter 56 cm in one

revolution is the circumference.

The distance= 2 into 22/7 into 28 = 176 cm

The distance covered by a wheel of diameter 56 cm in one

revolution is 176cm.
