What is the circumference of a circle if the radius is 3.5 yards?
The circumference of a circle is equal to 2 x pi x radius, where "pi" is approximately 3.1416.
If the diameter of a circle is 11 cm what is the radius?
The radius is equal to 1/2 the diameter. 11 divided by 2 =5.5
What is the area of 45mm diameter circle?
The area (A) of a circle is A = π . r2 The diameter (D) is equal to D = r / 2 . Were r is the radius. If the diameter of the circle is 45 mm, and we divide it by 2. We will obtain the radius which is equal to 22,5mm: D = 45mm / 2 = 22,5mm If we square this radius the result is 506,25mm2: r2 = (22,5mm)2 = 506,25mm2 So the area of the circle of diameter 45mm is: A = 506,25mm2 . π = 1590,43mm2d
What is the circumference of 8m radius circle?
Approximately 50.26m, because circumference is equal to diameter times pi (or 3.1415). Or twice the radius times pi.
What is the radius of a circle that is 7.1 cm?
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
Is the radius always equal to the diameter of a circle?
No, the radius of a circle is always 1/2 of the diameter.
Does the radius of a circle equal units from the center of the circle?
Yes. The radius of a circle is the distance from the centre of the circle to every point on its circumference.
Is a circle less than or equal to the radius?
The radius of a circle is the distance from the center of the circle, out to the edge of the circle. The distance all the way across the circle is the "diameter." Half of the diameter is the radius.
Circle with a radius of 8 feet equal what?
Circle with a radius of 8 feet equals a circle with a diameter of 16 feet.
The line which is at a distance equal to the radius of a circle from its centre is called?
Radius
What is the the length of a circle that has a radius of 30?
The circumference of a circle with radius 30 is equal to 2 times the radius times pi, or about 188.5.
What is equal to half the diameter of a circle?
the radius
What does it mean when the circumference of the circle is equal to the area of a circle?
the radius of the circle is 2 units
How many units in a unit circle?
A unit circle is a circle with radius equal to one.
What is the area of a circle which has a radius that is equal to1?
A circle with a radius of 1 unit has an area of 3.14 square units.
What is the radius of a circle having circumference equal 36 pie?
The radius is 18.
What is the diameter and area of a circle?
the diameter of a circle is defined by the largest length from one side of the circle to the other side of the circle. the area of a circle is equal to pi(3.14) times the radius squared. the radius is equal to half of the diameter.
