What is area of circle with radius 78 units

The space occupied within the boundary or circumference of a circle is defined as the area of a circle. It is the region occupied by the circle in 2D (Two-Dimensional).

The formula for the Area of the Circle is, $\textbf{A} = \boldsymbol\pi \boldsymbol\times \textbf{r}^ \textbf{2}$

Where,

A = area of the circle

$\pi$ (pi or Pythagorean constant) = $\frac{22}{7}$ or 3.14

r = radius of the circle (in m, cm, and so on)

$A = 3.14 \times 78^2$

$A = 3.14 \times 6084$

$A = 19103.76$

Therefore, Area of circle with radius 78 unit is 19103.76 sq. unit
