Answer:
Third option
Step-by-step explanation:
By observing the diagram we can see that the diameter of circular base is 6 inches. The diameter will be sued to find the radius.
r = 6/2 = 3 inches
We can also see from the diagram that lateral height denoted by l is 5 in.
We know that the formula for surface area of a cone is given by:
Comparing it with the options we get that the third option is correct ..
Answer: 5 cm
Step-by-step explanation:
B =
The true statement about right-angle triangle ABC is that: A. sin(A) = cos(C) and cos(A) = sin(C).
<h3>How to apply basic trigonometry?</h3>In order to determine the angles, we would apply basic trigonometry. From the diagram of the right-angled triangle shown below, we can deduce the following parameters:
By applying the basic trigonometry functions, we have:
sin(A) = Opp/Hyp = a/c.
sin(C) = Opp/Hyp = c/b.
cos(A) = Adj/Hyp = c/b.
cos(C) = Adj/Hyp = a/c.
From the above, we can logically deduce that sin(A) is equal to cos(C) and cos(A) is equal to sin(C).
