Question

if the radius of the wheels ofa bus is 0.7m . how much rotation will a wheel complete while traveling a distance of 22 km​

Answer 1

Answer:

Wheel would complete 5000 rotation while travelling a distance of a 22 km.

Step-by-step explanation:

circumference of wheel = 2 \pi r2πr

Here,

Circumference of wheel = 22 ×\frac{22}{7}722 ×0.70.7

Circumference of wheel = 2×2.2

Circumference of wheel = 4.4

Now,

it will take (\frac{22000}{4.4}4.422000 ) rotations to cover 22 km

it will take 5000 rotations to cover 22 km

❥︎ Question :-

• If the radius of the wheels of a bus is 0.7m. How much rotation will a wheel complete while traveling a distance of 22 km?

❥︎ Answer

❥︎ Given :-

• Radius of wheel of a bus, r = 0.7 m = 70 cm
• Distance covered by bus = 22 km = 22 × 1000 × 100 = 2200000 cm

❥︎ To Find :-

• Number of rotations to cover the distance of 22 km.

❥︎ Solution :-

Let number of rotations made by wheel of bus be 'n'.

Radius of wheel of a bus, r = 0.7 m = 70 cm

❥︎ We know, Distance covered in 1 rotation

$\bf\implies \:2\pi \: r$

❥︎ So, Distance covered in 'n' rotations

$\bf\implies \:2\pi \: rn$

❥︎ According to statement,

Distance covered by bus = 22 km = 2200000 cm

$\bf\implies \:2 \: \pi \: r \: n = 2200000$

$\bf\implies \:2 \times \dfrac{22}{7} \times 70 \times n = 2200000$

$\bf\implies \:n = 5000$

$\bf\implies \:number \: of \: rotations = 5000$
