10, i believe. i hope this helps :)
The area of a circle is Pi * R^2 (or R * R).
Since we have our radius, R, we can solve.
With our given answer choices, we do not need to multiply R by Pi, instead we will square R, as that's our only option.
4.5 x 4.5 = 20.25.
Our area is now 20.25Pi.
Your answer is C.) 20.25Pi.
I hope this helps!
Slope AB = 1/3
slope CD = -3
Im not sure about the last part but I think the product of slope AB and slope CD is -1 so line AB is perpendicular to line CD.
the workings are below:)
(so sorry if it’s wrong)
