Determine whether the conjecture is true or false. Give a counterexample for any false conjecture.

Given: Two angles are supplementary.
Conjecture: They are both acute angles.
Question 11 options:

False; either both are right or one is obtuse.

True

False; they must be vertical angles.

False; either both are right or they are adjacent.

The answer is false, either both are right or one is obtuse.

astronomers is your final answer! : )

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
