I don't know if this is what you are after, butthe circumference (not circumstance) C is 2*pi*r where r is the radius (not radious, as you spell it).
A circle does not have a circumstance. Assuming that you mean circumfernece, the answer is c = 2*pi*r
The circumstance of a circle is 2 x pi x radius. I.e.: if the circle has a radius of 6, the circumstances 12×π which is 37.6991118432
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
the equation for the circumference is Pi * double the radius which is 3.1416 * 15.5 * 2 The circumference of a circle with a radius of 15.5cm is 97.3cm.
radius
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
A circle does not have a circumstance. Assuming that you mean circumfernece, the answer is c = 2*pi*r
34 / pi
Circumference = 2*Ï€*radius = 20*Ï€ feet
The radius of a circle = the diameter of the circle divided by 2
The circumstance of a circle is 2 x pi x radius. I.e.: if the circle has a radius of 6, the circumstances 12×π which is 37.6991118432
The radius of the circle decreases when you make the circle smaller.
Standard equation for a circle centred at the origin is x2 + y2 = r2 where r is the radius of the circle. If you increase the size of the circle then the radius must increase, so r2 will be larger. eg a circle of radius 2 has the equation x2 + y2 = 4, if the radius increases to 3 then the equation becomes x2 + y2 = 9
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
The distance from any point on the circle to the origin
The inner circle is x2 + y2 = 4. The radius of the inner circle is the square root of 4, which is 2. To find the radius of the outer circle, multiply 2 times 4. The radius of the outer circle is 8. Square 8 (82 or 8 x 8) to find the number to put into the equation of the outer circle. This is 64. The equation for the outer circle is x2 + y2 = 64.
Radius = 1111
