A circle in the xy-plane has a center at (3/4, 1/2) and a radius that is 3/5 units long. Which of the following is an equation of the circle?

A. (x - 3/4) + (y - 1/2) = 3/5

B. (x - 3/4)^{2} + (y - 1/2)^{2} = 9/25

C. (x + 3/4)^{2} + (y + 1/2)^{2} = 3/5

D. (x + 3/4)^{2} + (y + 1/2)^{2} = 9/25

The general equation of a circle is given as:

(x - h)^{2} + (y - k)^{2} = r^{2}

where (h, k) is the cordinate of center and r is the radius.

Given the center as: (3/4, 1/2) and radius 3/5,

h = 3/4

k = 1/2

r = 3/5

Substituting the above values into the general equation,

(x - 3/4)^{2} + (y - 1/2)^{2} = (3/5)^{2}

(x - 3/4)^{2} + (y - 1/2)^{2} = 9/25
