Answer: 345.4
Step-by-step explanation:
SA=2πr^2+2πrh
SA=2(3.14)(5)^2+2(3.14)(5)(6)
SA=2(3.14)(25)+2(3.14)(30)
SA=2(78.5)+2(94.2)
SA=157+188.4
SA=345.4
To answer this problem, you should know the formula that we will be using and this would be:
Angle of elevation = arc tan( (vertical height)/(length of the shadow)).
Plugging in the values in the formula. Here, this angle is:
arc tan (12.5/18) = <span>34.78 degrees</span>
The answer would be approximately 34.78 degrees
-18x
you first times the numbers, which becomes -18
Next you add the exponent from the veriables (x) (if you're diving you're subtractiong example: x^a/x^b = x^a-b)
Sooo when you add them you get 8-7=1 which means.. x^1 (but you don't need to put the 1)
-18x
Here is the solution to it
Answer:
24 feet
Step-by-step explanation:
First, I used the proportion method to set up the numbers. I used x for the height of the tree.
x/45 = 6/11.25
Notice that the x and the 6 are both the heights of the tree and Dimitri and that they are both on the top of the fractions.
45 and 11.25 are the lengths of the shadows and they are both on the bottom of the fractions.
Next, I did 6 times 45 and got 270. Then I did 270 divided by 11.25 and got 24.
You're welcome! :)
