Answer:
12
Step-by-step explanation:
If you flip the polygon on the right so it looks like the polygon on the left, the scale factor for the small polygon to the big polygon is 32/40 or 4/5.
Now use that scale factor, 4/5, to find the missing length
4/5 = ?/15
5*3 = 15 so 4*3 = ?
? = 12
The diameter of the circle would be a line going through the center of the circle connecting to both sides.
The radius of a circle would be a line only going to the the center, or in other words, half the circle.
I hope this makes sense!
Answer:
My answer is 57.776

6.28× 9.2
= 57.776
Dunno about rounding it to tenths cause that would be 60
