what is the approximate volume of the composite figure? use 22/7 for pi. Round to the nearest hundredth. the shape is in the pic.

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.
