What is the circumference of a circle of radius 21?
The circumference is 42pi, or approximately 131.946864
What is the radius of a circle with a circumference of 21?
21/(2*pi) = a radius of about 3.342253805 units
What is the radius of a circle with a circumference of 21 units?
The radius is 3.34 units.
The circumference of a circle is 132cm what is the radius of the circle in centimeters?
To find the radius of a circle when given the circumference, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 132 cm, you can plug this value into the formula: 132 = 2πr. To solve for the radius, divide both sides by 2π: r = 132 / (2π) ≈ 21 cm. Therefore, the radius of the circle is approximately 21 centimeters.
if a circle has a radius of 21 what is the circumference?
C = 131.95
If the radius of a circle is 21cm What is the radius?
The radius of any circle is the straight line distance from the centre of the circle to any point on the circumference of the circle. The radius being 21 cm makes no difference to the definition of the radius; it just means that the straight line distance from the centre of that circle is 21cm away from any point on the circumference of that circle. The radius of a circle with a radius of 21 cm is 21 cm.
What is the radius of a circle with a 21 inch circumference?
the radius is 10.5 inches. * * * * * Wrong! Circumference = 2*pi*Radius Or, Radius = Circumference/(2*pi) So circumference = 21 inches implies radius = 3.34 inches (to 3 sf)
What is the circumference of 21 feet?
If you are talking about a circle then the circumference would be 65.97
