Q # 5 please help to resolve

Answer 1

If you mark 8 points on the circle you can get 28 segments.

The number of segments you can draw that connect these points is given by this equation:


`(1)/(2)n^2- (1)/(2)n`

So you need to find out the number of segments you can draw by marking eight point on the circle. Therefore, we set
`n=8` in the equation and let's get the number of segments that are drawn in the circle. So:


`(1)/(2)(8)^2- (1)/(2)(8) \\ \\ (64)/(2)- (8)/(2)=32-4=\boxed{28 \ segments}`

The correct answer is D. 28 segments.
