Heya Brainlians ⛄ !!
The wheels of a car are of diameter 80 cm each. How many complete revolutions does each wheel make in 10 minutes when the car is travelling at a speed of 66 km / hour ?
Thanks ❤

Answer:
HERE IS UR ANSWER...
Step-by-step explanation:
Diameter of wheel = 80 cm
Radius of wheel = 40 cm
Distance covered by wheel in 1 hour = 66 km = 66000 m = 6600000 cm
Distance covered by wheel in 10 minutes = 1100000 cm
No. of revolutions = 4375

GivenDiameter of wheel (D)=80 cmRadius (r)=
GivenDiameter of wheel (D)=80 cmRadius (r)= 2
GivenDiameter of wheel (D)=80 cmRadius (r)= 280
GivenDiameter of wheel (D)=80 cmRadius (r)= 280
GivenDiameter of wheel (D)=80 cmRadius (r)= 280 =40 cm.
GivenDiameter of wheel (D)=80 cmRadius (r)= 280 =40 cm.1 complete revolution of wheel = Circumference of wheel (C)
GivenDiameter of wheel (D)=80 cmRadius (r)= 280 =40 cm.1 complete revolution of wheel = Circumference of wheel (C)C=2πr=2π×40=80π cm
GivenDiameter of wheel (D)=80 cmRadius (r)= 280 =40 cm.1 complete revolution of wheel = Circumference of wheel (C)C=2πr=2π×40=80π cmC=0.8π m
