The arc length, radius and the included angle are related as
where 
is in radians.
The radius 
is given by
Correct choice is (B).
The diagram in the question is a cylinder.
;The volume of a cylinder is given by;
Volume = πr²h
;Where π=3.14
r⇒radius of the base of the cylinder and
h ⇒ height of the cylinder.
∴Volume = 3.14×5²×3
=235.5 ft³
To the nearest cubic = 236 ft³
B. Y= 2/5x +1 remember rise over run so you can figure out your first fraction and then look for where the line hits the y-axis so you know you y intercept
Answer:
only 4 is incorrect...
1,450,000 = 1.45 x 
NOT
1,450,000 = 1.45 x 
Step-by-step explanation:
answer: a. input, output
explanation: this is because the x values can not repeat in a function. if they do, they would not pass the vertical line test, and therefore it would not be a function. so, each input and output must be different values. :)
