What is the radius of the circle equal to?
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
What is the radius of a circle that is 7.1 cm?
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
The circumference of a circle is 132cm what is the radius of the circle in centimeters?
If the circumference of a circle is 132cm its radius is: 21.01 cm
What is the diameter of a circle with a 9 radius?
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
How do you find the circumfrence of a circle if you have the radius?
the circumfrence of a circle is pi times it's radius squared.
How do you express the area of a circle as a function of its radius?
If a circle has radius r, then the area of the circle is pi r2, pi being about 3.14159. I beleive the function you are looking for is A(c)=c/2*r
Is the radius of a circle a function of its area?
You can certainly express the radius as a function of its area, yes. If the area is known, you can solve the formula for the area of the circle to uniquely get the radius. (The quadratic equation has two solutions; you will of course choose the positive solution for the radius.)
What is the diameter of a circle whose radius is 85mm?
170mm. Diameter of a circle is two time the radius.
How do you represent the radius of a circle as a function of the circumference?
Circumference = 2 x pi x radius Therefore, radius = circumference / ( 2 x pi )
The circumference of a circle in cm is a function of the radius in cm This function is written Which is true about this function?
C = 2 x R x pi
Express the radius of a circle as a function of its area?
A = (pi)r2 A/pi = r2 √(A/pi) = r
Wha is the radius of a circle?
The radius of a circle is half the circle's diameter
What is the radius of a circle where d is the diameter of the circle?
the radius of a circle is r
What is the radius of the circle equal to?
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
If the radius of a circle is r what is the diameter of the circle?
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
Is the circumference of a circle a linear function of its radius?
Yes.You could also state that the circumference is directly proportional to the radius. The proportionality constant is (2 pi).
How do the the radius and diameter of a circle compare?
The diameter of a circle is twice its radius
