Step-by-step explanation:
Use
where r is radius (12) and h is height (17).
12^2=144
(144)(17)=2448

Answer:
k = 3
Step-by-step explanation:
Given that y and x are directly related then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 81 when x = 27
k =
=
= 3
Answer:
123 degrees
Step-by-step explanation:
Well, since we have a 4 sided figure, we know that the sum of the interior angles is 360 degrees.
(n-2)*180=(4-2)8180=360
Okay we are given 3 angles
120+43+74= 237
that means that x= 360-237
x=123 degrees
