It’s the heigh. Times the radius and volume
h= V/r
The trinomial that results from foiling the binomials is 6x^2+41x+30.
I would use the decimal form of 5.4%. It is very easy to convert a percentage into a decimal. All you have to do is move the decimal point two places to the left and remove the % sign.
5.4% = 0.054
So, 0.054 would be your multiplier.
Point slope form- y-4=(x+2)
Slope intercept- y=x+6
