Multiple choice

The circumference of a circle is $44$ m then the area of the circle is

  1. $\displaystyle 6084.5\:m^{2}$
  2. $\displaystyle 276.5\:m^{2}$
  3. $\displaystyle 154\:m^{2}$
  4. $\displaystyle 44\:m^{2}$

C Correct answer
Explanation

Circumference = 2 * pi * r = 44. So, 2 * (22/7) * r = 44, which gives r = 7. Area = pi * r^2 = (22/7) * 49 = 22 * 7 = 154.

AI explanation

Using the circle circumference formula 2 times pi times r equals 44, we get the radius r equals 7 meters when pi is approximated as 22 divided by 7. Now apply the area of circle formula, which is pi times r squared. Substituting the values gives 22 divided by 7 multiplied by the square of 7, yielding an area of 154 square meters.
