The area is 2*pi*12 = 2*pi.
Using pi = 3.14, that would give an estimated area of 3.14 cm2.
A circle can have a unit of length which could be either a measure of its diameter or radius, or of its circumference. Or the circle could have the unit of area.
You cannot. The circle could be located anywhere on a plane.
Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.
Your question implies that it could be the radius, diameter or even the chord of a circle in which the diameter is the largest chord of a circle.
Divide the diameter by 2.
You do not need to estimate it. You can calculate it as being pi*r2 which, in this case is pi square cm.
A square does not have a radius. A square, with sides of length x units, can have an inscribed circle. Such a circle would have a radius of x/2 units. Or the square could have a circumscribing circle. This would have a radius of x/sqrt(2) units.
A circle can have a unit of length which could be either a measure of its diameter or radius, or of its circumference. Or the circle could have the unit of area.
The radius of a circle is the distance from the center of the circle to the outer edge Also known as half of the diameter. The diameter is the distance from opposite edges of the circle going through the centre.
You cannot. The circle could be located anywhere on a plane.
It depends on the shape that is removed. It could be a smaller circle, whose radius is sqrt(2/3) = 0.8165 of the original radius, Or a circle with a hole with radius sqrt(1/3) = 0.5774 of the original radius cut out of it, Or a wedge making a central angle of 120 degrees removed from the circle, Or more complicated shapes.
Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.
the circumference of a circle is 3.4 but with the radiusof 3.5 it is........................... well i was hoping you could tell me!!!:)
Your question implies that it could be the radius, diameter or even the chord of a circle in which the diameter is the largest chord of a circle.
OK, The circumference of a circle is 2 times pi (3.14) times the radius. SO the radius is = to circumference (5cm) divided by 2 times pi. 5 divided by 6.28 = .796 time 2 gives us a diameter of = 1.59 centimeters. We could also use Pi = cicumference/diameter therefore 3.14=5/x Multiply both side by x and 3.14 x = 5 Divide both sides by 3.14 and you get x= 5 divided by 3.14 which equals 1.59 cm
i am not sure but i could surly use some help
Divide the diameter by 2.
