Those two angles are congruent(corresponding), so we can set these equal to each other.
19x+3=21x-3
-2x=-6
x=3
Answer:
a) 16
b) Using
is more accurate because it represents the exact and full value of pi, rather than an estimation or approximation like 3.14.
Step-by-step explanation:
The formula to find the volume of a cone is
. We know the radius is 6, so all we need to find is the height, h. By using the Pythagorean theorem, we can see that the height is
, or 8. Plugging in all the values into the formula gives us:
V = 
V = 16
Hope this helped! :)

Total = Principal * (1 + rate/n)^n*years where "n" is the number of compounding periods
Total = 9,250 * (1 + .07/52)^52*5
Total = <span>9,250 * (1.0013461538</span>)^260
<span><span>Total = 9,250 * 1.418733571
</span>
