Answer: 110 square cm
=======================================================
Explanation:
All sides of a regular polygon are the same length. So the bottom side is also 8 cm.
Draw lines from the center to each vertex of the pentagon. Five triangles form. Each triangle has a base of 8 and a height of 5.5 (since all five triangles are congruent)
area of one triangle = 0.5*base*height = 0.5*8*5.5 = 22
area of five triangles = 5*(area of one triangle) = 5*22 = 110
Answer:
25 pounds, hope its right
Step-by-step explanation
Answer:
A = 
. r^2
If A = 9ft^2
. r^2 = 9ft^2
r^2 = 9ft^2
r = sqrt(9ft^2)
r = 3ft ( r>0)
