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.
