Use the picture of the circle below to find the area of the circle. Use 3.14 for π and show your work.

254.34 in^2

Step-by-step explanation:

To calculate the Area of Circle is πr^2

r is the radius of the circle

In this problem, the diameter is given which is 18 in. To find the radius you have to divide the diameter by 2.

18/2 = 9 in is our radius

Area of Circle = π9^2

                       = 3.14*81

                       = 254.34 in^2                    

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.
