Find the diameter of the base of a right cylinder if the surface area is 128(pi) and the height is 12cm.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

0 is its x and y coordinate
