Answer:
last oneeee
Step-by-step explanation:
In regular polygons, if the number of sides, n, is odd, the lines of symmetry will pass through a vertex and the half of the opposite side.
Step-by-step explanation:
This is equivalent to say that a perpendicular bisector of a side of the regular polygon bisects the angle of the opposite vertex to the side, and divide the polygon into two symmetrical parts.
Are you kidding me, bro? lol
276-115=131
131 divided by 276 = 0.47
0.47% increase
Radius is 142
You must find the diameter
Want to find diameter you need to take the number of radius is 142 Multiply 2
= 284
The circumference is 284
A = pi r^2
531 = 3.14 ( r^2)
169.12 = r ^2
Take the square root
13 = r
Diameter = 2r
D = 2(13)
D = 26 mm
