What are the center and the radius of the following circle whose equation is x^2 + y^2 + 4x = 5? What is the center and radius of the circle with equation (x + 9)^2 + (y + 5)^2 = 64? What are the center and radius of the circle whose equation is x2 + y2 + 4x = ...
Here, the radius is the distance from the circle’s center to its edge, and pi is a mathematical constant approximately equal to 3.14159. Triangle: For a triangle, the area formula is one-half the base times the height (A = ½ x b x h). This formula is used when you know the ...
If we perform a linear rescaling around the axis of the fat tube by a factor of to turn it into a tube, this would inflate the thin tubes to be rescaled tubes of dimensions , which would now be -separated in direction. This rescaling does not affect the multiplicity of the tubes. ...
Proposition 1 (Iterative approximation) Let be a Banach space, let be sets with each contained in the ball of radius around the origin for some with convergent, so that the infinite sumset is well-defined. Suppose that one has some convergent series in , and sets converging in norm to zer...
Pi, a mathematical constant denoted by the Greek letter π, is the ratio of a circle's circumferenceCto its diameterd: π = C/d. The circumference of a circle is, in turn, equal to 2πr, whereris the circle's radius. No matter how big or small a circle is, this relationship will...
How does 5 divided by 0.5 equal 10 ? In this problem, you will prove that pi is irrational. Assume that pi is rational; in particular, assume that pi = p q where p and q are positive, coprime integers. Let f ( t ) = t n ( p ? q t What is 11 divided by 12 as a fractio...

The radius (r) of this circle is equal to the mass (m) times the square of the velocity (v) divided by the centripetal force (F), or r = mv^2/F. The force can be calculated by simply rearranging the equation: F= mv^2/r. Newton's third law states that "for every action, ...
Euclid's postulates were :Postulate 1 : A straight line may be drawn from any one point to any other point.Postulate 2 :A terminated line can be produced indefinitely. Postulate 3 : A circle can be drawn with any centre and any radius. Postulate 4 : All right angles are equal to one...
