2.8 A mass density in space is given by ρ(r, z) ¼ r(r + a) + z(z + d) kg/m3 (in cylindrical coordinates). (a) Calculate the total mass of a cylinder of length d, radius a, centered at the origin with its axis along the z axis.
(b) Calculate the total mass of a sphere of radius a centered at the origin.

no one knows lol

step-by-step explanation:

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
