Using your algebra skills, how can you rearrange the formula for the volume of a cone, , to find an expression for radius r when you're given h and v? remember to perform the same operations on both sides of the equation.

Volume of a cone:

//Multiply 3 on both sides:

//Divide πh on both sides:

//Square root both sides:

//Rewrite with r as the subject:

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

okay wait before i answer, is this for your points on a graph?
