3x-12y = 5
-x+3y = 9

First step is to make the coefficient of either x or y same.

3x-12y = 5
(-x+3y = 9)3

3x-12y = 5
-3x+9y = 27

-4y = 32
y = -8

Answer:

i believe the answer is 142.42 in²

Step-by-step explanation:

what i did was 'separate' the cone and cylinder-

so the volume of cylinder formula is-

v=πr²h

and the volume for a cone is-

v=πr²h/3

now let us fill in the formulas with the information that we have-

v=π*2²*10=125.66

v=π*2²*4=16.76

now let us add the sums together-

125.66+16.76=142.42 in²

good luck :)

i hope this helps

**please let me know if this is incorrect/not what you're looking for or both**

have a nice day!
