The wheels on a car have a diameter of 28 inches. How many full revolutions will the wheels need to make to travel 200 feet?
Answers
Answer:
27.28 revolutions or ≅ 682/25 revolutions
Step-by-step explanation:
Diameter of wheels (d) = 28 inches
Concept:
Circumference of wheel = Distance traveled by 1 revolution of wheel
Therefore,
Circumference = π.d = π 28 = 87.96 inches or 7.33 feet (1 feet = 12 inches)
Therefore for traveling 200 feet,
Number of revolutions = Distance traveled/Circumference
= 200/7.33 = 27.28 revolutions
Answer:
28 revolutions
Step-by-step explanation:
The wheels on a car have a diameter of 28 inches. How many full revolutions will the wheels need to make to travel 200 feet?
1 revolution = Perimeter of wheel
Perimeter of wheel = 2 π R
π = 2/7 R =radius = Diamtere / 2 = 28/2 = 14 inch
Perimeter of wheel = 2 * (22/7) * 14 = 88 inch
12 inch = 1 feet
88 inch =88/12 feet = 22/3 feet
22/3 feet is traveled in 1 revolution
1 feet is traveled in = 1/(22/3) = 3/22 revolutions
200 feet is traveled in = 200 * 3/22 = 300/11 = 27.27
= 28 revolutions
