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.

What is the circumference of a circle with a diameter of 15 inches and a radius of 7.5 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.
If the radius of a circle is 2cm what is the diameter?
Diameter of circle = 2 * Radius of the circle.
What is half of a diameter of a circle called?
The radius of the circle.
If the Diameter of a circle is 120 what is the radius?
Since diameter is twice its radius, the radius of this circle would be 60
What is the radius of a circle with a 6.2 cm diameter?
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.
What is the radius of a circle with a diameter of 15 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
What is the radius of a circle whose diameter is 15 meters?
The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
If the diameter of the circle is 30 mm then what is the radius of the circle?
The radius if the circle is half of its diameter and so 30/2 = 15 mm
How do you find the radius of a circle if diameter is 15 centimeters?
Radius is half of the diameter
What is the diameter of a circle in centimeters that has a radius of 15 mm?
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.
What method can be used to find the radius of a circle whose diameter is 15?
radius = diameter/2
If the diameter of a circle 30 cm what is its radius?
The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 cm.
What is the diameter of a circle that has a radius of 7.5 in?
15 inches.
If the radius of a circle is 15 inches what is the diameter?
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
What is the diameter of a circle whose radius is 7.5 centimeters?
Diameter is twice the radius, so 15 cm.
A circle of a radius has 15find the diameter and area?
diameter is 15 area of the circle is... 706.5 if im not mistaken
What is the radius of a circle that has a diameter of 15 cm?
7.5Radius of circle: 15/2 = 7.5 cm
