Answer:
r=8
Step-by-step explanation:
V=πr^2h
You know volume and height so plug that in.
2211.68=πr^2(11)
and solve for r.....
Area = 1/2 x base x height
120 = 1/2 x 15 x base = 15/2 x base
base = (2 x 120)/15 = 16 in.
You have no number values there; the best I can do is tell you that c = 360-a-b-d. Since b and d are the same measure, we can rename d as b, so your equation is c=360-a-2b. But since a and c are the same, rename a as c to get an equation of c=360-c-2b. Now add c to both sides to give you 2c=360-2b and c=180-b. Can't do anything else with no values.
<span>The correct answer would be option C. Similar polygons
Similar polygons are polygons wherein the corresponding angles are congruent and the corresponding sides are proportional with each other. Thus, having a pair of similar polygons would mean that its corresponding angles would always be congruent.</span>
