A diameter of a circle is twice the length of a radius. Think of a diameter as two radii, both originating at the center of the circle and extending out at 180 degrees to each other to reach the edge of the circle. In this example, if the radius is 1.5, the diameter would be 3.
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.
Diameter of circle = 2 * Radius of the circle.
The radius of the circle.
Since diameter is twice its radius, the radius of this circle would be 60
The radius (radii) of a circle is 1/2 of the diameter. The radius of a circle with a 6.2 cm diameter is 3.1 cm.
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
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 radius if the circle is half of its diameter and so 30/2 = 15 mm
Radius is half of the diameter
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
radius = diameter/2
The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 cm.
15 inches.
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
Diameter is twice the radius, so 15 cm.
diameter is 15 area of the circle is... 706.5 if im not mistaken
7.5Radius of circle: 15/2 = 7.5 cm
