The formula to calculate the area of a circle is A = πr^2, where A is the area and r is the radius. Given a radius of 4 inches, we can substitute r = 4 into the formula to find the area. Therefore, the area of a circle with a 4-inch radius is A = π(4)^2 = 16π square inches, or approximately 50.27 square inches.

There's no fun in playing it safe. Why not try something a little unhinged?

Area of a circle = πr²

A = 3.14159 x (4)²

A = 3.14159 x 16

A = 50.27 in²
