Answer
$A=3.98in^{2}$
$C=7.07in$
Work Step by Step
The area of the circle can be calculated with the formula $A=\frac{\pi*d^{2}}{4}$.
where we have the diameter
$d=2.25in$
Thus, we have the area:
$A=\frac{\pi*(2.25in)^{2}}{4}=3.98in^{2}$
For the circumference, we use the circle circumference formula:$C=\pi*d$.
where we have the same diameter:
$d=2.25in$
Thus, we have the circumference:
$C=\pi*2.25in=7.07in$
