Answer:
16pi cm2
Step-by-step explanation:
Area of a circle = pi * radius * radius = pi * 4 cm * 4 cm = 16pi cm2
Sum of internal angles of any polygon is: (n-2)x180
So measure of an interior edge is ( ( n - 2 ) x 180 ) / n = 140
So 140n = 180n - 360
40n = 360
n = 9
So it's a nonagon.
Hope this helps :)
250 + 100 = 350
350 + 1000 = 1350
1350 / 5 = 270
