Answer:
D.
Step-by-step explanation:
The length of the unmarked side of the triangle is found by using Pythagoras:
x sqrt (10^2 - 6^2)
= sqrt 64
= 8.
The length of the curved part = 1/2 * pi * 10 = 5pi
Perimeter = 8 + 6 + 5pi
= 14 + 5pi
Let the unknown side be "z" inches
Through pythagoras:

Because the square of the two sides add up to the square of the hypotenuse in a right triangle.
This means that



So the missing side is 16 inches
