The volume of right circular cylinder a is 22 cubic cm. what is the volume in cubic cm of a right cylinder with twice the radius and half the height of cylinder a

Find the center and the radius of the circle with the equation: x^2-2x+y^2+4y+1=0?

To find the inverse of a number a, one can use the equation f(c) = a-1/c=0 where c is the inverse of a use the secant method of finding roots of equations to find the inverse of a = 2.5 ,er = 0.001%

Is (0,0) a to ? ys x2 - 4 y> 2x-1
