The diameter of a circle is 105 cm less than the circumference what is the diameter of the circle?
Correct answer: D. 49 cm
- A. 44 cm
- B. 46 cm
- C. 48 cm
- D. 49 cm
Explanation
Using circumference C = πd, we have πd - d = 105 cm, so (22/7 - 1)d = 105 cm. Thus (15/7)d = 105 cm and d = 49 cm; option a, 44 cm, does not satisfy the stated difference.

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.
