What is the formula for the circumstance of a circle where r represents the radius of a circle and c represents the circumstance of a circle.?
A circle does not have a circumstance. Assuming that you mean circumfernece, the answer is c = 2*pi*r
What is Circumstances of a circle?
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
What is the equation of the circle standard form?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
What is the circumference of a circle with a radius of 15.5cm?
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.
The of a circle centered at the origin measures the distance from the origin to any point an the circle?
radius
How do you find the radius of circle with area 144pi?
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

What is the radius of a circle with a circumstance of 68?
34 / pi
Which equation can be used to find the circumference of a circle with a radius that measures 10 feet?
Circumference = 2*Ï€*radius = 20*Ï€ feet
What is the equation for the radius of a circle?
The radius of a circle = the diameter of the circle divided by 2
How To find the standard equation for a circle centered at the origin we use the distance formula since the radius measures?
To find the standard equation for a circle centered at the origin, we use the distance formula to define the radius. The equation is derived from the relationship that the distance from any point ((x, y)) on the circle to the center ((0, 0)) is equal to the radius (r). Thus, the standard equation of the circle is given by (x^2 + y^2 = r^2). Here, (r) is the radius of the circle.

When you make the circle smaller which number in the standard equation for a circle centered at the origin decreases?
The radius of the circle decreases when you make the circle smaller.
When you make the circle bigger or smaller which number of the standard equation for a circle centered at the origin changes?
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
If you Give a circle with a diameter of 4 what is the circumference?
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
To find the standard equation for a circle centered at the origin you used the distance formula since the radius measures?
The distance from any point on the circle to the origin
The equation of the inner circle is x2 plus y2 equals 4 the radius of the outer circle is four times the radius of the inner circle write the equation of the outer circle?
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.
