30 inches
The radius of a circle is half of its diameter. Therefore, if the diameter is 15 inches, the radius would be 15 inches divided by 2, which equals 7.5 inches.
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
15 inches.
Circumference = Pi multiplied by the diameter. C = (3.1415)(15 in.) = 47.12 in. Therefore, the circumference of a circle with a diameter of 15 in. and a radius of 7.5 in. is approximately 47.12 inches.
The radius of a circle is half the diameter, thus your measurement is 30 inches
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
To find the area of a circle, you can use the formula A = πr², where r is the radius. For a 15-inch diameter circle, the radius is 7.5 inches. Thus, the area is A = π(7.5)² ≈ 176.71 square inches.
The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
The diameter of a circle is defined as the distance across the circle through its center. For a circle with a diameter of 15 inches, the diameter is simply 15 inches. Therefore, the diameter of a 15-inch circle is 15 inches.
Radius is half of the diameter
If the radius is 2 then the diameter is 2*2 = 4 inches and the circumference is about 12.6 inches and not 15 inches
30 inches. The diameter is twice the length of the radius.
