The diameter of a wheel of a heavy load vehicle is \(\frac{7}{2}\) feet. If the wheel makes 26…
The sum is approximately 298. The circumference is \(7\pi/2\) feet, so \(x=26(7\pi/2)=91\pi\) and \(y\) \(=132/(7\pi/2)\) \(=264/(7\pi)\). Thus \(x+y\) \(=91\pi+264/(7\pi)\)…
Choose your answer
The diameter of a wheel of a heavy load vehicle is feet. If the wheel makes 26 revolutions the vehicle moves a distance x feet. If the vehicle moves 132 feet, the wheel makes y revolutions. The sum of numerical values of x and y is approximately
Answer and explanation
Correct answer A
The sum is approximately 298. The circumference is feet, so and . Thus , which rounds to 298.
