Question

What is the area of a regular pentagon with a side length of 10 inches and a distance from the center to a vertex of 10 inches?
Round your answer to the nearest tenth.


A. 216.5 sq in.
B. 228.5 sq in.
C. 242.5 sq in.
D. 251.5 sq in.

Answer 1

Side = 10in.
Radius = 10in.

Formula = \(\dfrac{5}{2}sr\)

Plug it in:

\(\dfrac{5}{2}(10)(10)\)

Multiply:

\((25)(10)\)

Can you multiply that? @raeluvpop
