volume - pi*r^2*H
Lets use 3.14 for pi
R = radius which is half the diameter so half of 3 is 1.5
H = 6
so volume = 3.14*1.5^2*6 = 42.39in^3
Answer:
y=2x
Step-by-step explanation:
Y=kx

Answer:
D. cosine
Step-by-step explanation:
As it can be seen in the figure, the triangle ABC is a right-angled triangle with Angle C = 90 degree.
In a right angle triangle, there is a formula as following:
<em>cosine (of an acute angle) = length of adjacent side/ length of hypotenuse</em>
In the figure, the point of angle B and length of hypotenuse AB are given.
We have to calculate x - length of the given side. As BC is the adjacent side of angle B
=> we can use the above formula to calculate x
So that we can use cosine
