If , the diameter of the circle is 7cm
and the area of the shaded portion is 27.5m^2
, find, correct to the nearest degree,
the value of x.

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.

the radius is 2 times the diameter.

step-by-step explanation:

you just switch the numbers basically so it would be 3/17
