Question

The difference between the circumference and the radius of a circle is $74cm$, find the area of the circle.

Answer 1

According to the problem:

Difference$=2\pi r-r$

$r\left(2\pi -1\right)=74$

Solving

$r=14$

Area of circle=$\pi r^2$

$=\frac{22}{7}\times {\left(14\right)}^2$

$=616$
