Answer:
3054.0ft³
Step-by-step explanation:
Given parameters:
Height of cylinder = 12ft
Base radius = 9ft
Unknown:
Volume of the cylinder = ?
Solution:
The volume of a cylinder is the product of its base area and height;
Volume of cylinder = base area x height
= πr²h
r is the radius
h is the height
Insert the parameters and solve;
v = 3.142 x 9² x 12 = 3054.0ft³
Answer:
D
Step-by-step explanation:
Because if you add 11 to 6 it will be bigger than 14 so it will not be the solution set
Those lines on both sides of the number means "absolute value." Those lines tell us that the number is positive no matter what. So:
15 + |-3| - 4 → 15 + 3 - 4
Remember to follow PEMDAS when solving.
(15 + 3) - 4
18 - 4
14
Therefore, the answer is 14.
Best of Luck!
Answer:
Your answers are correct except the 7th
7th Answer : 6 + 5a
Step-by-step explanation:
12) 2a - 8 = 14 ⇔ 2a = 22 ⇔ a = 11
13) 2(a + 3)
16) 3x - 1 = 7 ⇔ 3x = 8 ⇔ x = 8/3
