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.
I have 65 square feet of pavers What diameter circle will this make?
3.14 x (r x r) 9 foot diameter circle
How do you find the director circle of circle?
The director circle of a circle with radius r is a concentric circle with radius r*sqrt(2).
What happens to the area of a circle when the radius is tripled?
The area of the circle becomes 9 times the area of the original circle. Original circle = Pi * (r ^ 2) = Pi * r * r New Circle = Pi * ((3 * r) ^ 2) = Pi * 9 * r * r
What is the approximate circumference of circle r?
Circumference of a circle with radius 'r' = 2(PI)(r) ~ 6.28(r)
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.
How do you make the circle-R tradmark symbol show up?
Alt + 0174 = ®
Which number in the standard equation for a circle centered at the origin should one increase to make the circle larger?
You should increase the radius in the standard equation of a circle centered at the origin. The general form is ( x^2 + y^2 = r^2 ), where ( r ) is the radius. By increasing ( r ), you extend the distance from the center to any point on the circle, making it larger.
What does r in the circle mean?
R = Radius The radius is half the diameter of a circle.
Help with math how do you get the area of a circle?
Area of a circle is calculated by A=2*p*r where A represents the circle's area and r is the radius of the circle.
How do you find the area of a half circle?
Make it a whole circle. Find the area. Divide by two.
How do you get the square foot of a circle?
You want the area of a circle, which is pi*r2 Just make sure your radius (r) is in feet and you answer will be square feet.
