A cylinder has a radius of 5 and height of 3. what is the volume

Lapatulllka [165]

Answer:

236 cubic units (to 3 significant figures)

Step-by-step explanation:

volume of a cylinder = $\pi$ r²h (where r = radius and h = height)

Therefore, volume = $\pi$ x 5² x 3

= $\pi$ x 25 x 3

= 75 $\pi$

= 236 cubic units (to 3 significant figures)

2 = (-x) Help I'm a not so bright blonde!

makvit [3.9K]

If you need to solve this equation you can multiply the both side of equation on (-1). Like that
2 = (-x);
-1·2 = (-1)·(-x)
if you multiply negative and positive you'll have negative,
if you multiply negative and negative you'll have positive. So

-2 = x. or
x = -2.
The answer is -2.
