We have that
solution is
x <-10 or x>=25

for
x < -10
the solution is the interval (-∞, -10)

and 
for 
x>=25
the solution is the interval [25,∞)

therefore
the solution for
x <-10 or x>=25
is
(-∞, -10)  ∪ [25,∞)

<span>the solution is any value of x less than -10 or greater than or equal to 25</span>

A cylinder has height of 7 inches and a base with a diameter of 9 inches.
bekas [8.4K]

Answer:

527.6 cubic inches

Step-by-step explanation:

The volume of a cylinder is represented by the formula V = \pi r^{2} h, where r represents the radius of the base and h represents the height.

In this question, the diameter is given as 9 inches. Since the radius is half the diameter, the radius will be 4.5 inches.

Substituting in the values and solving, we get:

V =9 \pi (4.5)^{2}\\V = 9\pi(20.25)\\V = 182.25\pi\\V = 572.6

The Volume will be 527.6 cubic inches
