Circumference of 9 inches: 2.864788975654119in. (for pi I used 3.14159265358979)
Diameter of 9 inches:
4.5in.
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.
The radius of a circle with a 14.5 inch circumference is 2.15 inches
1 inch
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
radius of 31 inches
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. For a 12-inch circle, the radius is half of the diameter, so the radius is 6 inches. Therefore, the area of the 12-inch circle is A = π(6)^2 = 36π square inches. Similarly, for a 9-inch circle, the radius is 4.5 inches, so the area of the 9-inch circle is A = π(4.5)^2 = 20.25π square inches.
The area is 254.47 in2
A circle with a 12 inch diameter has a 6 inch radius.
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.
The radius of a circle with a 14.5 inch circumference is 2.15 inches
A four-inch radius circle has an area of about 50.27 square inches.
12 inch
1 inch
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
radius of 31 inches
The Diameter of a Circle is twice the Radius.thus for a 52 inch Diameter Circle the Radius will be 52/2=26 inches.
