\large\blue\textsf{\textbf{\underline{\underline{Question:-}}}}

What is the area of a circle with a radius of 4?


\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}


\textsf{Formula for Area of a Circle :}


\dashrightarrow\star\bigstar\boxed{\boxed{A=\pi r^2}}}

Where

  • A = Area
  • π = pi (3.14…)
  • r = radius (we're given that it's equal to 4 units)

Using the provided information, we substitute the values into the formula:-


\bold{A=\pi (4)^2}

First, square the radius:-


\bold{A=16\pi }

Now multiply:-


\bold{A=50.3\:units^2}

Good luck.
