Answer:
Answer choice 4. 577 pounds
Step-by-step explanation:
Given a cylindrical steel post with dimensions:
- Radius = half of diameter = 0.5 * 6 = 3 inches [converting to feet, we need to divide inches by 12, so we have feet ]
Volume of a cylinder is given as:
Volume =
Substituting all the given values we have:
cubic feet
<em>Since, 1 cubic foot of steel weights 490, 1.1775 cubic foot of steel would weigh </em>
Rounding to nearest pound, we would get pounds as the answer.
Answer choice 4 is correct.
Answer:
r = 8
Step-by-step explanation:
Solve for r:
r + 4 = 12

4 - 4 = 0:
r = 12 - 4
12 - 4 = 8:
Answer: r = 8

x = 5√2
Not sure what the question is.
<u>9</u>+2x=18
Subtract 9 from each side then...
<u>2</u>x=9
Divide each side by 2 and you'll have that x is....
x=4.5
