In the diagram, O is the center of a circle with radii OP=OQ=5. What is the perimeter of the shaded region?

Sorry, but I don't see a diagram. Could you please include it?

:)

Oh I forgot sorry, Here is the diagram

@P = $3/4($ 2rpi ) +& 2r

If the questions can be "camouflaged", so can the answers.

I'm not sure what that means

Calculate the circumference of the complete circle. Take 3/4 of that and add to it the lengths of OP and OQ (which are radii of the circle).
