Question

A regular decagon has a radius of 8 cm. What is the approximate area of the decagon? Recall that a decagon is a polygon with 10 sides.

A) 188 cm^2
B) 198 cm^2
C) 304 cm^2
D) 375 cm^2

Answer 1

A is the correct answer

Explanation:

Answer 2

The anwer is A) 188cm^2

Explanation:

the area formula using radius is

r^2sin(360/n)

a=---------------------

2

a=64sin(360/10)

-----------------------

2

a=188
