Okay if you do these four problems for me you get 17 points check the screenshots

for j i think is 2179. and for g is 1/25 or as a decimal 0.04

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
