The equation for the circle below is x2 plus y2 81. What is the length of the circle's radius?
9 (APEX)
The equation for the circle below is x2 plus y2 equals 121 What is the length of the circles radius?
11 = sqrt of 121. it is a circle centred on the origin think what would happen on the line x=0 (The y axis) the equation simplifies to y2 = 121 or y =11 you can also think of eqn of a circle as x2+y2=r2
If the length of a diameter of a circle is10what is the length of a radius of this circle?
The radius is 1/2 of the diameter. A diameter of 10 has a radius of 5.
How do you determine length and width of a circle?
there is no length or width of a circle. There is radius and circumference and the line that goes all the way through the center to the other side of the circle, which is twice the radius. But there is no length or width of a circle.
Is the ratio of the radius to the diameter of all circles?
The ratio of radius to diameter for any circle is 1/2
Can a circle be drawn with any center and any radius?
The center of a circle is the same for all circles but the length of the radius can change
The equation for the circle is x2 plus y2 equals 121 What is the length of the circle's radius?
Radius = 1111
How can you tell what a circles equation is?
The equation for any circle is r2 = (x-a)2 + (y-b)2 Where r is the radius and the centre of the circle is (a,b)
This circle is centered at the origin and the length of its radius is 5 What is the equation of the circle?
x2 + y2 = 25
This circle is centered at the origin and the length of its radius is 4 What is the equation of the circle?
x2 + y2= 16
This circle is centered at the origin and the length of its radius is 5 What is the circle's equation?
x2 + y2 = 25
This circle is centered at the origin and the length of its radius is 6 What is the circle's equation?
x2 + y2 = 36
This circle is centered at the origin and the length of its radius is 7 What is the circle's equation?
x2 + y2 = 49
What is the length of the circles radius for the circle x2 plus y2 169.?
The equation x^2 + y^2 = 169 represents a circle centered at the origin with a radius of 13 units.
How do you find the radius of a circle if you know the length of a chord is 4 cm length?
Unless the chord is the diameter, there is no way to measure the radius of the circle. This is because the radius is in no way dependent on chord length since circles have infinite amount of chord lengths.
How do you find the diameter of a circle if you have the circumference?
C=2(3.14)rThis is circumference equation for circles. If you have the circumference, you need to input it into the equation and solve for r. r is the radius of the circle, so to determine the diameter, which is 2 times the length of the radius, you just need to multiply the number you got for r times 2.
Circle A has a radius that is twice the length of circle B What is an accurate statement about the areas of both circles?
Circle A has more area than B
