True:1/4 is an example of a terminating decimal
(x-y)^2 +4xy = (x+y)^2
FOIL
x^2 -2xy+y^2 +4xy = (x+y)^2 x^2 -2xy
Combine like terms
x^2 +2xy +y^2 = (x+y)^2 x^2 +2xy
Factor
(x+y)^2 = (x+y)^2 (x+y)^2
Answer:
The diameter is twice that, or approx. 7.90 units.
Step-by-step explanation:
the equation for the volume of a cylinder of radius r and height h is
V = πr²h. Here we need to calculate the diameter after having found the radius. Solving V = πr²h for r², we get:
V
r² = -----------
πh
Substituting the given values, we obtain for r² the following:
145 units³
r² = ------------------------ = 15.6 units²
3.14159(5 units)
Taking the square root of both sides, we get:
r = √15.60, or approx. 3.95 units.
The diameter is twice that, or approx. 7.90 units.
