Hi there!
The formula for the lateral area of a cylinder is LA = 2 x pi x r x h. (two times pi times radius times height) Using this formula, we can plug in the values and solve for the lateral area.
Plugging in the values: LA = 2 x pi x 7 x 9
Simplifying: LA = 2pi x 63
LA = 126pi yd^2
ANSWER:
The 4th option - 126pi yd^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
1 cm = 10 millimetres
10 cm = 100 millimetres
100 cm = 1,000 millimetres = 1 metre
Therefore:
4 metres = 4,000 millimetres
I think at 6pm he will get caught up, correct my calculations if im wrong.
Answer:
d = 56x + 412
Step-by-step explanation:
To find the total number of miles traveled on Monday and Tuesday, use a linear equation to write the function.
y = mx+b where m is the speed or rate of change and b is the starting point.
The starting point on Tuesday is 412 miles. This is b.
The number of miles traveled on Tuesday is found by calculating 56 miles times the number of hours traveled. This is the slope or m.
So the equation is d = 56h + 412.
Here is the equation:
In the equation, 6 is being multiplied by x - 8. There are two ways to solve this equation.
FIRST METHOD
<h3>
</h3>
You need to remove the parentheses by multiplying everything in the parentheses by 6.
Multiply:
Remember:
NEGATIVES
- Negative(-) times(×) negative(-) = positive(+)
- Negative(-) times(×) positive(+) = negative(-)
- Negative(-) divided(÷) by positive(+) = negative(-)
- Negative(-) divided(÷) by negative(-) = positive(+)
POSITIVES
- Positive(+) times(×) positive(+) = positive(+)
- Positive(-) times(×) negative(-) = negative(-)
- Positive(+) divided(÷) by positive(+) = positive(+)
- Positive(+) divided(÷) by negative(-) = negative(-)
Now combine the two values and rewrite the equation:
Since you're looking for x alone, you will need to remove the -48. This can be done by adding 48 to both sides, -48+48=0, which cancels it out).
Lastly, divide both sides by 6 to leave x alone.
SECOND METHOD
While the first step is somewhat complicated, there is a much easier way.
Start by dividing both sides by 6 to remove the number next to the parentheses.
(The 6 is cancelled out since 6 divided by 6 equals 1, and 1 × any number is that number).
Now you need to leave the variable alone, which can be done by adding 8 to both sides(-8+8=0 and -8 is cancelled out).
Either method can be used, but the second one is definitely shorter!
The answer is x = 20.
