tell me if it works
A kg is 1000 grams, so you would 1000*4.
Answer:
923.63
Step-by-step explanation:
the formula for the surface area of a cylinder is 2πrh + 2πr^2 ( i just looked it up lol)
The formula for volume of a cylinder is V=π r^2 h.
So plug in,
320π=<span>π r^2 20
solve (sadmep (opposite of pemdas))
divide pi out
320=r^2 20
divide 20 out
16=r^2
square root of 16 is 4, so the radius is 4.
Since the 2r=d, the diameter is 8.
P.s. lol it thought I was copying an answer from online...

When using substitution , you substitute with a variable that is already by itself. In this case, the variable “y” is already by itself and equal to x+ 1.75 . you substitute that for the the y in the other equation and solve for the other variable which is “x”. After you solve for x , to find your y value, you have to substitute the x value in for either equation.
