The radius of a wheel is 22.4 cm. What is the distance covered by the wheel in making 500 resolutions.

Correct answer: B. 704 m

  • A. 252 m
  • B. 704 m
  • C. 352 m
  • D. 808 m

Explanation

One revolution covers the wheel's circumference: 2π x 22.4 cm = 140.8 cm, using π = 22/7. In 500 revolutions, the distance is 500 x 140.8 cm = 70,400 cm = 704 m. Option c can result from forgetting the factor of 2 in the circumference.

About Area and Volume

Area measures the surface enclosed by two-dimensional figures, while volume measures the space occupied by three-dimensional solids. Problems use formulas for rectangles, triangles, circles, prisms, cylinders, cones, spheres, and composite figures, including unit conversion and the distinction between surface area, lateral area, and volume.
