Answer ! will give and 30 ! when a circular pizza is cut into six slices using diameters, the total length of the cuts is 18 cm. what is the area of the pizza in square centimeters?

Hey there!

This tells us that the cuts add up to 18 cm. There is 3 cuts that make 6 slices. 18/3=6 cm for the diameter of the pizza. The equation to find the area of the circle is Area=π r^2 (radius squared). Divide the diameter by 2 to get the radius. 6/2=3. Plug this in for r. A=π 3^2. Simplify this to A=9πcm^2. The units for area is units^2. So the area would be 9πcm^2.

I hope this helps!

Remark
I am deliberately putting an answer in so that you can choose a for the other responder. My answer will not be on topic, so you can choose the other person quite easily.

I found it interesting that all regular polygons with sides of 4 and above that are even will be a possible solution to your pizza problem. The circle enclosing the regular polygon will have diameters running through the center if the opposite vertices are connect. I've uploaded three of them. I cannot prove this is so, but it is an interesting fact.

The left one is a decagon
The middle one is an 18 agon (I don't know the proper term)
The right one is a 14 a gon (again I don't know the proper term)

Conclusion
1. Probably all even vertici regular polygons have this feature in common.
2. Next time you order a pizza, think about the regular polygon that created the cuts.
