Find the area of a circle with a diameter of 16 inches. use 3.14 for pi.
a.50.24 in2
b.100.48 in2
c.200.96 in2
d.251.2 in2
i keep getting 201.06in² but that is not one of my choices. can someone explain what i'm doing wrong?

200.96

Step-by-step explanation:

Diameter of the circle = 16 inches

Radius of the circle = 16/2

                               = 8 inches

pi = 3.14

Then

Area of the circle = pi (Radius)^2

                           = 3.14 * (8)^2

                           = 3.14 * 64

                           = 200.96 square inches

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
