Answer:
D. 5.32 cubic units
Step-by-step explanation:
Volume of a cone = ⅓πr²h
Radius (r) = 1.52 units
Height (h) = 2.2 units
π = 3.14
Substitute
Volume = ⅓*3.14*1.52²*2.2
Volume = 5.32 cubic units

I’m not so sure about this one but my guess would be maybe C

Step-by-step explanation:
Answer:
(x, y) = (40, 30)
Step-by-step explanation:
A graphing calculator can show you the solution to this system of equations is (x, y) = (40, 30). That is the point of intersection where the two lines cross.

An algebraic solution can be found by using the substitution method. An expression for y can be found using the second equation:
y = 110 -2x . . . . . . subtract 2x from both sides
Using this in the first equation gives ...
3x -4(110 -2x) = 0 . . . . substitute for y
11x = 440 . . . . . . . . . simplify, add 440
x = 40 . . . . . . . . . . divide by 11
y = 110 -2(40) = 30
The solution is (x, y) = (40, 30).
