Whose side S1 is given by the cylinder x 2 + y2 = 9, whose bottom S2 is the disk x2 + y2 ≤ 9 in the plane z = 0, and whose top S3 is the part of the plane z = 3 + x that lies above S2. Sketch S first, indicate S1, S2, and S3 then evaluate.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
