- 1 < - x/3 < 1
1st. Multiply all parts by 3:
-3 < - 3x/3 < 3. Simplify the mid term:
-3 < -x < 3. Now multiply all terms by - 1. Note when you multiply by a negative number, you flip the inequality signs:
(-1)(-3) < (-1)(-x) < (-1)(3)
+3 > x> -3
Answer:
351.9 cubic in
Step-by-step explanation:
The volume of a cylinder is hr²π.
r is half the diameter, so 8/2 is 4.
Plug in your h and r and get:
7 * 4² * π
7 * 16 * π
112π
Multiply the π and you'll get about 351.9 cubic in
Good morning,
Answer:

Step-by-step explanation:
h = altitude
side = a
using Pythagorean theorem: in the right triangle:
h² = a² - (a/2)²
= a² - a²/4
= 3/4a²
= [(√3/2)×a]²
⇒ h = (√3/2)×a.
