If the half circle is on its flat side, the radius is its height. If the straight part of the half-circle is vertical, the radius is its width.
Half the diameter of a circle is called its radius.
Radius is half the length from one side of a circle to the other or half the diameter.
The diameter of a circle is twice the radius. A radius is half of a diameter.
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
3.9cm. The Radius is always half the diameter of a circle.
An oval is a general word that could have different shapes. If you squash a circle evenly, the new shape in math is called an ellipse, which has an oval shape. The formula for the area of a circle is Pi times the Radius of the circle squared. The radius is half the height of the circle and also half the width of the circle. The general formula for the area of an ellipse is Pi times half the height times half the width. So we say length A is half the height of an ellipse and length B is half the width of an ellipse. When A is equal to B you have a circle. When they are different you have an ellipse. So if you want the area of the circle to be the same as the area of the ellipse, then you have to keep the height times the width the same for the ellipse as it was for the circle. As you squash the ellipse further the width must stretch out more than the height gets pushed down. For example, a circle with radius of 1 inch would have the same area as an ellipse with height ½ inch and width 2 inches because 1 times 1 is equal to ½ times 2. Another ellipse with the same area could have height ¼ inch and width 4 inches.
radius is half and diameter is the whole Expanding theabove statement: Diameter is the width of a circle; Radius is one half the width. In math, the radius refers to the distance from the centerpoint of a circle out to the edge.
The term "radius" only applies to circles, and is half of the circle's width (or diameter). For rectangles, you have a width and a height, and the area is calculated by multiplying width by height. A square's width and height are equal, so if a square is 5" wide, then the area is 25 square inches (25in2). Circle areas are calculated by multiplying the radius by itself, and multiplying the result of that by pi (π), or about 3.14. A circle with a radius of 5" would be 3.14*5*5, or 78.5in2 (78.5398 to be more accurate).
You mean radius. The radius is half the height of a circle. The diameter is the full height. So, you would add 14 to itself.Therefore, the diameter of the circle is 28 inches.
If you have a physical cylinder to measure, measure the "width" of the circle that is the cross section of the cylinder. That is the diameter, Half the diameter is the radius.
The radius is 32 because the height of the hemisphere (which is half of a sphere) is the same thing as the radius (which is half the length of the diameter); the radius is the distance from the center to any point on the edge or surface of the circle/sphere.
The radius is half of the diameter, so just divide the diameter by two, and area is width x height.
The diameter is the whole width of the circle across the middle. The radius is the distance from the middle to the edge, so is half the diameter. Therefore the radius would be 8 cm
The radius of the circle.
The center of the rectangle to the corner of the rectangle is the radius of the circle. That can be found using the distance formula sqrt((5/2)^2+(12/2)^2) = 6.5 = r 5/2 is half the height of the rectangle and 12/2 is half the height of the rectangle. radius = 6.5
half of the radius the radius is half of the diameter the diameter is the with of the circle. This also can be called a quadrent circle.
No. A diameter divides a circle in half. A radius is half the diameter.
