\pi r \sqrt{ h^{2} + r^{2} }

You put in the values you know and you get 829.4

To find the surface area you use the equation

\pi r(r+ \sqrt{ h^{2} + r^{2} }

Put in the values you know and you get 1209.5

Answer:

? = 85°

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5 , then

sum = 180° × 3 = 540°

sum of the angles around a point = 360° , so

interior angle on right = 360° - 250° = 110°

sum the interior angles and equate to 540°

110° + 115° + 120° + 110° + ? = 540° , that is

455° + ? = 540° ( subtract 455° from both sides )

? = 85°
