Question

If π is taken as $\frac{22} {7}$ , the distance (in metres) covered by a wheel of diameter 35 cm, in one revolution, is
(a)2.2
(b)1.1
(c)9.625
(d)96.25

Answer 1

Answer:

The distance (in m) covered by a wheel in one revolution is 1.1 m.

Among the given options option (b) 1.1 m is the correct answer.

Step-by-step explanation:

Given :  

Diameter of a wheel = 35 cm

Radius of a wheel ,r = 35/2 cm

Distance covered by the wheel in one revolution = Circumference of the wheel  

Circumference of the wheel, C  = 2πr

C = 2 × 22/7 × 35/2

C = 22 × 5  

C = 110 cm

C = 110/100  

[1 cm = 1/100 m]

C = 1.1 m

Distance covered by the wheel in one revolution = 1.1 m  

Hence, the distance (in m) covered by a wheel in one revolution is 1.1 m.
