The Pythagoras is the sum of the square of two sides is equal to the square of the longest side, then the length of the apothem is 6.5 cm. Then the correct option is D.
What is Geometry?
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The pentagon is shown.
The side length of the pentagon is 9.4 cm.
And the distance between the center and the vertice of the pentagon is 8 cm.
Then the length of the apothem (x) is given by the Pythagoras theorem.
x² = 8² - 4.7²
x² = 64 - 22.09
x² = 41.91
x = 6.47 ≅ 6.5
