Solve for π: V= 2πr^2 + 2πrh

Mathematics
1 answer:
crimeas [40]4 years ago
3 0

Answer:

π = V/(2r²+2rh)

Step-by-step explanation:

"Solving" for something means to isolate it on one side of an equation. Because both terms on the right side of the equation have π in common, we can factor it out. Then from there, you just divide the rest of it on both sides to isolate π. It should look like this:

V=2πr^2 + 2πrh

V=π(2r² + 2rh)

V/(2r² + 2rh)=π

Contact [7]
Hint:  Please express exponentiation with the "^" symbol:  x^2 - x - 2.

Note that the final term factors to (-2)(-1), and that -2x and +1x combine to produce the middle term, -x.  Thus, the factors of this polynomial are

(x+1)(x-2).

There are 20 small tropical fish swimming in a 55-gallon aquarium. What is the population density?
umka21 [38]

Answer:

The population density is 0.364 fish per gallon.

Step-by-step explanation:

The population density can be defined as the number of individuals (in this case, small tropical fish) per unit of area or volume. In this case, the volume of the aquarium (55 gallon).

The density can be calculated then as:

d=\dfrac{P}{V}=\dfrac{20\;\text{fish}}{55\;\text{gal}}\approx0.364\dfrac{\text{fish}}{\text{gal}}

The population density is 0.364 fish per gallon.
