Step-by-step explanation:
Size of Interior angle = 180° - 360°/n, where n is the number of sides of the regular polygon.
We have 180° - 360°/n = 160°.
=> 360°/n = 20°, n = 18.
Therefore it is a 18-sided regular polygon.
Well if you want to simplify you can do it to ways
1 leave it how it is because you cant simplify anymore
or
2 turn it into a mixed number
first see how many times you can fit 8 into 27
8*2=16 8*3=24 8*4=32
so it is 3 times
and you have 3 left over so that goes over 8 and your simplification is 3 3/8

Answer:
c
Step-by-step explanation:
Answer:
Answers below
Step-by-step explanation:
Radius = 3m
Diameter:
d = 2r
d = 2(3m)
d = 6m
Circumference:
c = 2πr
c = 2π(3m)
c = 6π m
c = 18.85 m
Area:
A = 2πr^2
A = 2π(3m)^2
A = 18π m^2
A = 56.55 m^2
