Mar 12, 2018 · How do I find the radius of a circle from its general equation? How can a general equation tell me whether a conic section is a circle or an ellipse? What conic section does the equation #x^2 + 4y^2 - 4x + 8y - 60 = 0 # represent?

Jan 7, 2016 · The answer would be 18.8495559215 units. The formula for finding the circumference is 2pir. We can plug in 3 for r, getting 2pi3.

Sep 8, 2015 · The area of a circle is given by the formula #color(white)("XXX")A = pir^2# where #A# is the area of the circle, #color(white)("XX")r# is the radius of the circle, and

Mar 12, 2018 · The approx volume is 113 cc. As given, the formula for the volume of a sphere (not circle) is V = 4/3 * pi*r^3 Plugging in your data V = 4/3 * pi * (3 cm)^3 = 113.1 "cc" I hope this helps, Steve

Oct 30, 2016 · How do I find the radius of a circle from its general equation? How can a general equation tell me whether a conic section is a circle or an ellipse? What conic section does the equation #x^2 + 4y^2 - 4x + 8y - 60 = 0 # represent?

Nov 25, 2015 · It is: (x+3)^2+(y+4)^2=9 The equatyion of a circle whose center is at C=(a,b) and radius is r is: (x-a)^2+(y-b)^2=r^2

This is not the case. If we are given the radius and the perpendicular height, the volume will be the same as a right cylinder of the same height and radius. This is easier to see if we look at the volume as a series of discs. From the two stacks we can see that the height remains the same and the volume of each disc also remains the same.

Jan 20, 2016 · The standard form of the equation of a circle is : # (x - a )^2 + (y - b )^2 = r^2 # where (a , b ) are the coordinates of the centre and r = radius .
