I used 3.14 as pi
Step by step explanation:
SA= 2(pi*r²) + (pi*d)h
SA= 2 ( * 4² ) + (pi*8)*6
<u>you could also do this:</u>
SA=2πrh + 2πr²
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis.
According to the statement data we have:
Thus, the equation is of the form:
We substitute the given point and find the cut-off point:
Finally, the equation is:
We manipulate algebraically to obtain the standard form:
We multiply by 3 on both sides of the equation:
We multiply by -1 on both sides:
