Answer:
The answer is 527.5km^3 .
Step-by-step explanation:
The formula for cylinders is πr2h. (pie times twice the height)
3.14(12)(2)(7) = 527.52
If you mean the x, it would be 50
Hello! I can help you with this!
4.
a. $100
b. $360
The formula to find the answers to these kinds of problems is p * r * t. The rate is always a decimal, so if the rate is 8%, you multiply by 0.08. If the rate is 12%, you multiply by 0.12, and so on.
5.
a. 12.8
b. 31 1/6
I got these answers by doing the distributive property. Replace each variable with the number it represents, multiply each by two and add them up to get these answers. For the fraction one, you can set up each fraction by finding the LCD before multiplying by 2, or you can find a fraction calculator online and add the numbers up.
6.
a. x = 20
b. x = 3
c. x = 13
d. x = 0
e. x = 4
f. x = 7
g. x = -3
I solved this problem by doing the distributive property and doing these kinds of problems step by step. It’s long to explain, but hopefully your teacher has good notes for you to look back on over these types of questions. If there is only a negative sign in front of the distributive property equation, then you basically distribute -1 to each number. In these long equations, combine like terms. You must do these kinds of questions right, because it’s easy to mess up and get wrong answers if you don’t do the right steps in order.

Answer:
The area of the hexagonal table will be 27 square feet
Step-by-step explanation:
Given:
The height of the triangle = 3 feet
The base of the triangle = 3 feet
To Find:
The area of the hexagonal table = "
Solution:
<u>Step 1: Finding the area of the triangle</u>
The area of the triangle =
On substituting the values
The area of the triangle is =
The area of the triangle =
square feet
<u>Step 2 : Finding the area of the hexagonal table </u>
The area of the hexagonal table is = 6 X area of one triangle
The area of the hexagonal table = 
The area of the hexagonal table = 
The area of the hexagonal table = 27 square feet
