GIVEN :
=> THE DIAMETER OF A WHEEL :
=> 44 CM
_____________________________
TO FIND :
=> THE DISTANCE COVERED IN 450 REVOLUTIONS ....
_____________________________
STEP 1 :
=> TO FIND THE CIRCUMFERENCE OF THAT WHEEL
______________________________
TO FIND THE CIRCUMFERENCE WE NEED THE RADIUS
RADIUS :
=> DIAMETER / 2
=> 44 / 2
=> 22 CM
______________________________
CIRCUMFERENCE OF THE WHEEL ( CIRCLE ) :
=> 2 * π * R
=> 2 * 22 / 7 * 22
=> 44 / 7 * 22
=> 138.285 CM
______________________________
STEP 2 :
=> TO FIND THE DISTANCE COVERED IN 450 REVOLUTIONS
______________________________
WE CALCULATED THE DISTANCE COVERED BY THE WHEEL IN 1 REVOLUTION :
=> 138.285 CM
______________________________
DISTANCE COVERED IN 450 REVOLUTIONS :
=> DISTANCE COVERED IN 1 REVOLUTION * 450
=> 138.285 CM * 450
=> 68,228.25 CM
______________________________
STEP 3 :
=> TO CALCULATE THIS DISTANCE IN METER :
______________________________
1 M = 100 CM
=> WHEEL COVERED DISTANCE OF 68,228.25 CM ....
IN METER ,
=> 68,228.25 / 100
=> 682.2825 M

Given,
Diameter of Wheel of the Scooter
Distance travelled by scooter for 450 revolutions of it's wheel = ? mts
Find the Radius of the Scooter's Wheel
Shape of the Scooter's Wheel is a Circle
For a Circle, We have,
Substituting Values
Find the Circumference of the Scooter's Wheel
We have,
Substituting Values
The Circumference of the Scooter's Wheel = 138.28 cm
Find the Distance travelled by Scooter in 450 revolutions of it's wheel(in cm)
Distance travelled by Scooter in 'n' revolutions of it's wheel is equal to product of Circumference of wheel and no. of revolutions made by the wheel.
Given no. of revolutions made by the Scooter's wheel, n = 450
Substituting Values
Express the distance travelled by the scooter in 450 revolutions of it's wheel in mts
We have,
