Answer:
140°
Step-by-step explanation:
The opposite angles in a parallelogram are congruent, thus
∠ K = ∠ M = 140°

carry out LCM method:
LCM of y and x is xy
![= \frac{x - 2y}{xy}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7Bx%20-%202y%7D%7Bxy%7D%20)
Answer:
B
Step-by-step explanation:
It is B because to find the volume you multiply all three values together, which gets you 68.448. I multiplied 9.2x3.1, which got me 28.52, and then I multiplied 28.52 by 2.4 which got me 68.448.
Answer:
Step-by-step explanation:
Prove this:
volume of cylinder = volume of cone + volume of sphere
πr²h = (1/3)πr²h + (4/3)πr³
Note that the factor πr² is common to all three of these formulas. Factoring out this πr², we get:
h = h/3 + (4/3)r
or: 3h/3 = h/3 + 4r/3
or: 3h = h + 4r
or: 2h = 4r
or: h = 2r
Note that 2r is the diameter of the sphere, and that this diameter is twice the radius. Thus, in view of the givens. this equation h = 2r is correct.
Thus, the volume of the cylinder is equal to the volume of the cone PLUS the volume of the sphere.
