Answer:
Height=9/2=4.5
A=1/2*b*h
A=1/2*6*4.5
A=13.5
13.5*2=27
The area of the shaded region is 27.
And isosceles triangle always equals 180 degrees so to find the value of x what number would you need for the value to be 180
<h3>
Answer: Choice D. 12,600 feet</h3>
============================================================
Explanation:
We have two similar triangles here, so we can set up the proportion below to solve for x
5200/(5200+6500) = 5600/x
5200/11700 = 5600/x
5200x = 11700*5600 .... cross multiply
5200x = 65,520,000
x = (65,520,000)/(5200)
x = 12,600 which shows why the answer is choice D
side note: 12,600 ft = 2.386 miles approximately
The formula for a cylinder V= pi r squared times the height. I should suppose you were told to abbreviate pi to 3.14. First do 6 to the power of 2 which is 36 then multiply it by 3.14 witch would be 113.04. Then multiply that by 11.5 which would be 1299.96
The answer is 1299.96
