Answer:
C. ECA = BDA
Step-by-step explanation:
An angle is said to be produced whenever two or more lines meet at a point. An interior angle is an angle form within two lines meeting at a point. Then, alternate interior angles are internal angles that are equal due to alternate theorem. These angles should have equal measures.
From the given question, the alternate interior angles by the theorem is;
ECA = BDA
By the alternate interior angle theorem, the alternate interior angles are ECA and BDA. This implies that the measure of <ECA should be equal to the measure of <BDA.

Answer:

Step-by-step explanation:
Given
--- height of the cylinder
--- the diameter of the hemispheres at both end and the cylinder
See attachment for pontoon
Required
Determine the volume
First, calculate the radius (r)



Next, the volume of the cylinder



Two hemispheres make up a sphere. So, we simply calculate the volume of a sphere.



So, the volume of 1 pontoon is:



The volume of both is:
