Question

elite the diameter of a wheel is 1.26 m what the distance covered in 500 revolution

Answer 1

$in \: 1 \: revolution \: it \: covers = 2 \times \pi \times 1.26 \div 2 = 1.26\pi \\ in500 \: revolution = 500 \times 1.26\pi \\ = 630\pi$

Answer 2

QUESTION.

the diameter of a wheel is 1.26 m what the distance covered in 500 revolution

ANSWER.

GIVEN

Diameter of a wheel = 1.26m

=
$1.26 \times 100$

$126 \: cm$

Number of revolution = 500

FORMULA USED

Circumference of a circle= 2πr

Diameter =

$\frac{1}{2} r$

NOW BACK ON QUESTION

$radius \: of \: wheel = \frac{1}{2}d$

$radius \: of \: wheel = \frac{1}{2} \times 126$

$radius \: of \: wheel = 63cm$

$circumference \: of \: circle \: = 2 \times \ \pi \times 63$

$= 2 \times \frac{22}{7} \times 63$

$2 \times 22 \times 9$

$396 {cm}$

DISTANCE COVERED BY 500 REVOLUTION

$= 500 \times 396$

$= 198,000 {cm}$

IN METER

$= 198000 \times \frac{1}{100}$

$= 1980 m$
