The volume of a cylinder is 441π cubic centimeters and its radius is 7 centimeters. what is the height of the cylinder?

height =  9cm

Step-by-step explanation:

The volume of a cylinder is given as 441π cubic centimeters and it radius is 7 centimeter . The height can be computed as follows;

volume of a cylinder = πr²h

volume of the cylinder = 441π

where r = 7 cm

Therefore,

πr²h = 441π

π × 7² × h = 441π

49πh = 441π

divide both sides by π

49h = 441

divide both sides by 49

h = 441/49

h = 9cm

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)

∠cbe and ∠deb are same-side interior angles.
