Answers
Step-by-step explanation:
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
hope it helps u please mark me as brainliest
