Answer:
To find the sum of interior angles in a polygon, we can use the formula:
where n is the number of sides.
Since this is pentagon (5 sides), then
The missing angle would then be
Since angles on a straight line add up to 180, then
The volume is given by
Since the height is 3 times the radius of the base, we can substitute :
And we know that the volume is (I'm actually assuming that there's a typo in the question, otherwise the options wouldn't match):
The height is 3 times the radius, so it is
