To find the area of a circle in square inches, you can use the formula ( A = \pi r^2 ), where ( A ) represents the area and ( r ) is the radius of the circle. If you have the diameter instead, you can first find the radius by dividing the diameter by 2, and then apply the formula. The value of ( \pi ) is approximately 3.14 or can be used as the constant in calculations for more precision.

How many sq. inches in a 18 inch circle?
To find the area of an 18-inch circle, you can use the formula for the area of a circle, which is A = πr², where r is the radius. The radius of an 18-inch circle is 9 inches (half of the diameter). Therefore, the area is A = π(9 inches)² = π(81) ≈ 254.47 square inches.
If the area of a circle is about 28 sq inches the diameter of the circle is about?
If the area of a circle is about 28 square inches the diameter of the circle is: about 6 inches (5.971).
What is the area of a 93-inch circle?
If you mean a circle with a 93 inch diameter - it will have a 46.5 inch radius, giving it an area of ~6792.909 sq inches = ~47.173 sq ft. If you mean a circle with a 93 inch circumference - that will have a diameter of ~29.6 inches (radius of ~19.8 inches) and an area of ~688.3 sq inches = ~4.78 sq ft.
What is the area of the largest circle which can be cut from a square of edge 4 inches what is the area of the material wasted?

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 radius of the area of a circle that is 380 sq inches?
The radius of a circle with an area of 380 sq inches is 11 inches.
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.
What is the circumference of a circle with an area of 144 pie sq in?
To find the circumference of a circle with an area of 144π sq in, we first need to find the radius of the circle. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the area is 144π sq in, we can solve for the radius: 144π = πr^2, r^2 = 144, r = 12 inches. The circumference of a circle is calculated using the formula C = 2πr, so for a circle with a radius of 12 inches, the circumference would be 24π inches.
