How many square inches are there in a 6 inch diameter circle?

To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. In this case, the radius is half of the diameter, so the radius is 3 inches. Plugging this into the formula, we get A = π(3)^2 = 9π square inches. Since π is approximately 3.14, the area is approximately 28.26 square inches.


How do you find how many more square feet a 30 in circle is than a 18 in circle?

Area of 30 inch circle = pi*302 sq inches Area of 18 inch circle = pi*182 sq inches Difference = pi*(302 - 182) = 576*pi sq inches 1 sq foot = 1 ft*1 ft = 12 inches*12 inches = 144 sq inches so 576*pi sq inches = 576/144 *pi sq ft = 4*pi sq ft = 12.57 sq ft.

What is the circumference of a circle with an area of 144 pie sq in?

Oh, dude, you're hitting me with some math here. So, to find the circumference of a circle with an area of 144π square inches, you first need to find the radius by taking the square root of the area divided by π (r = √(144π/π)). Once you have the radius, you can calculate the circumference using the formula C = 2πr. So, the circumference would be 24π inches. Cool, right?


What is the area in feet of a 12 inch circle?

The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius of the circle. Since the diameter of the circle is 12 inches, the radius would be half of that, which is 6 inches. Converting inches to feet (1 foot = 12 inches), the radius would be 0.5 feet. Plugging this into the formula, the area of a 12-inch circle would be approximately 0.785 square feet.
