Area of circle = Pi x r^2

                      = Pi x [(3/4) / 2]^2

                      = Pi x [3/8]^2

                      =9/64Pi in^2

The area of the circle can be found, using $\pi r^2$

Since $\frac{3}{4}$ is the diameter, then the radius should be $\frac{1}{2}*\frac{3}{4}=\frac{3}{8}$

Plugging the value into the formula, we have: $\pi\frac{3}{8}^2=3.14*\frac{9}{64}$

But, since the answer box wants the fraction, we get: $\boxed{\frac{9}{64}}$
