The area of a circle is 24.64Sq.m. the circumference of circle is________?

Correct answer: C. 17.60m

  • A. 14.64cm
  • B. 16.36m
  • C. 17.60m
  • D. 18.40m

Explanation

For a circle, A = pi r², so r² = 24.64 m² ÷ (22/7) = 7.84 m² and r = 2.8 m. Therefore circumference = 2 × 22/7 × 2.8 m = 17.6 m. The likely trap is 16.36 m, which comes from using an unsuitable approximation or an incorrect rearrangement of the area formula.

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.
