Question 1145402: A regular 16-gon is inscribed inside a circle, as shown in the figure below. Sixteen congruent isosceles triangles are created by connecting the center of the circle to each vertex of the 16-gon. The base length of one of the isosceles triangles is b, and the height is h. The length of one of the lines connecting the center to a vertex is r.
We can find the area of the 16-gon by taking 16 times the base length b (in other words, by taking the ____1_____ of the 16-gon) and multiplying by h2. The ____2_____ of the 16-gon is close to the area of the circle. Therefore, the value of h is very close to the value of ____3_____ .
Select the terms that correctly fill in blanks 1, 2, and 3 in the previous sentences.
3: r
3: circumference
3: perimeter
2: diameter
2: area
2: perimeter
1: perimeter

Turn on your mind (it is inside your head, in case if you don't know it; or should be there).
