First convert the total km's to miles:
4.8 km / 1.609 km per mile = 2.983 miles.
Now convert miles to feet:
2.983 miles x 5280 feet per mile = 15,751.39 feet Rounds to 15,751.40 feet
27pi
3/4 * r^2*pi = 36 * 3/4 * pi = 27 pi
Answer:
<h2>n = 72</h2>
Step-by-step explanation:
Using the addition property add 7 to both sides
That's
Next multiply both sides by 3 to eliminate the fraction
That's
We have the final answer as
<h3>n = 72</h3>
Hope this helps you
Because this triangle is equilateral, AC = AB. Thus, 2x+7 = 4x-7, or
14 = 2x, or x = 7. Side BC therefore has length 4(7) = 28 (answer)
