Answer:
213.52 cubic ft
Step-by-step explanation:
Diameter of pipe = 4ft
radius for circle is half of diameter
thus radius of pipe = 1/2 of 4ft = 2 ft
length of pipe = 17 feet
volume of cylinder is given by
where r is the radius and l is the length of cylinder
.
thus volume of pipe is calculated below using above values
volume of pipe is 213.52 cubic ft.
Answer: x≤ 11/3
Step-by-step explanation:
Let's solve your inequality step-by-step.
6x+15≤37
Step 1: Subtract 15 from both sides.
6x+15−15≤37−15
6x≤22
Step 2: Divide both sides by 6.
6x

Answer:
(x - 9)(x + 8)
Step-by-step explanation:
Given
x² - x - 72
Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 1)
the factors are - 9 and + 8, since
- 9 × 8 = - 72 and - 9 + 8 = - 1, thus
x² - x - 72 = (x - 9)(x + 8)
