Please tell me the answer of this question.
Ques. The diameter of a wheel of a car is 70 cm. How many revolutions will it make to travel 99km.​

Answer 1

Answer:

Hey mate,here's your answer

Step-by-step explanation:

The tire tread length for a single revolution is its circumference, which is 2 x Pi x R. The radius of the tire, R, is half the diameter. So that’s R= D/2. R= 70 cm / 2 = 35 cm. Let’s calculate the radius in km. Its 35 cm x 1m/100cm x 1 km/1000m = 0.00035km. The tread length = 2 x 3.14 x 0.00035 km = 0.0022 km. the number of revs is 1.65 km / tread length = 1.65 km / 0.0022 km = 750.

Hope it helps you.
