Find the circumference of a circle with radius 5 ft.Area of a circle. The area of a circle of radius r is given by the polynomial πr2. Use 3.14 as an approximation for π.
It depends on the size....circumference is the length of the sides (combined) so it just depends how big the rectangle is
Circumference of a circle = pi DCircumference of the big one = 12 piCircumference of the small one = 8 piDifference = (12 pi - 8 pi) = (12 - 8) pi = 4 pi = 12.5664 inches (rounded)
360 degrees are in a circle no matter how big or small the circle is A circle has 360 degrees.
In math a compass is an object used to draw accurate circles and arcs (parts of circles, or curves). In math, a compass is something that makes a circle and it also measures circumference. How to make a circle: A compass either has led in it or you stick a pencil in it, but it depends on what kind of compass it is. If you want to make a big circle, you expand the 2 sides. when you get it to the size you want, you stick it on paper and twirl it around. It may not be a perfect circle but it most likely will be close.
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
well it depends how big the circle is
The circle has a diameter of 6.366 inches.
Any circle's circumference can be calculated with the formula 2(pi)*radius
A wheel is in the shape of a circle. The formula for the circumference of a circle is 2πr where r is the radius. But, the diameter of a circle is twice the radius so this equation can be written, Circumference = πd where d is the diameter. The Circumference is therefore π times as big as the diameter, π = 3.142 or 22/7 approx.
no because it all depends on how big the circle is.
I'm not sure, but that would make one big pi. <groan> Diameter x pi = circumference 27 ft x 3.141 = ___
Area is the space or room inside a circle and circumference is like the perimeter or the distance around a circle. In terms of pepperoni pizza, area is the cheesey pepperoni and circumference is the crust. On a plate, area is were you can place food and circumference is the edge.
You do not specify if the 8 mm is the circumference, diameter or radius. Please clarify.
The equation for finding the circumference of a circle is diameter times pi so reverse it to circumference divided by pi which leaves the diameter. The diameter is twice as big as the radius so divide the diameter by 2 and you will find the radius.
If you triple the radius of a circle . . . -- You should not expect anything to happen. Those around are likely to remain completely unaware that you have done anything to your circle. -- You wind up with a circle that's three times as big as it used to be. -- The diameter of the circle is three times the original diameter. -- The circumference of the circle is three times the original circumference. -- The area of the circle is nine times the original area.
The radius is the straight line distance from the centre of the circle to any point on the circumference of the circle. It can be measured in 'mm', or 'inches' or other units both metric and imperial .
