What is the diameter of a circle with a radius of 1cm?
2cm; the diameter of a circle is twice its radius.
What is the radius of a circle that has a diameter of 2cm?
1
Area of a 2cm circle?
Area= pi*r2If the diameter of the circle is 2cm, the A= pi cm2If the radius of the circle is 2cm, then: A=3.14159*4=12.567 cm2
If the diameter of a circle is 4 centimeters what is the length of the radius?
Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.
What is the diameter of a circle if the radius is 2cm?
The radius is double the diameter so 4cm.
What is the area of the circle if the radius is 2cm?
The area is 12.57 cm2
If the radius of a circle is 2cm what is the diameter?
Diameter of circle = 2 * Radius of the circle.
What is the area of a circle - radius 2cm?
The area is 22*pi, or 4pi or approximately 12.56 sq cm.
How do you work out the area of a circle given the diameter?
you half the diamater to get the radius, then you square the radius. Then you times it by 3.14. Always. example. Diameter=4cm then radius =2cm squared=4cm 4x3.14=12.56
What is the area and circumference of a circle with a radius 2Cm?
Diameter of 2 cm radius circle is pi x r2 = 3.1416 x 4 cm2 = 12.5664 cm2 Circumference of 2 cm radius circle = pi x 2r = 3.1416 x 4 cm = 12.5664 cm
What is volume cylinder of radius 4cm and height 2cm?
A cylinder with a radius of 4cm and a height of 2cm has a volume of 100.53cm3
On calculator what is the circumference of a circle with a radius 2cm?
The formula to calculate is: πD (or 2πr) On calculator, π=3.141592654 So it would be 12.56637062cm
