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.
What is the radius of a circle with a 14.5 inch circumference?
The radius of a circle with a 14.5 inch circumference is 2.15 inches
What is the radius of a 2 inch circle?
1 inch
What is the radius of a circle with a 6inches diameter?
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
What is the circumference of a circle with a 9 inch radius?
(pie)(diameter)=(circumference) (pie)(9)(2)=18(pie)=56.549
What is the area of a 12 inch and a 9 inch circle?
If you are talking about 9 and 12 inch diameter, then divide both by 2 to get the radius. The area of a circle is pi (3.1415 is good for most calculations) multiplied by the square of the radius. So for the 12 inch circle, the radius is 6. The square of the radius is 36, and multiplying this by pi gives approximately 113.1 square inches. Now the 9 inch circle has a radius of 9/2 or 4.5. Squaring this we get 20.25, which multiplied by pi is approximately 63.6 square inches. If 9 and 12 were already the radius in the problem, just don't divide by 2 since you already have the radius.
What is the area of a circle with a 9 inch radius?
The area is 254.47 in2
What is the radius of a circle with a 12 inch diameter?
A circle with a 12 inch diameter has a 6 inch radius.
