Answer:
For the expression if they don't want you to include the variables then I would write 3.14(6 + 4) or 3.14(2*3+2²). For the surface area, your answer is 31.4 units.
Step-by-step explanation:
If r = 2 and s = 3, then just plug them into the equation 3.14(rs + r²)
3.14(2*3+2²)
= 3.14(6+4)
=3.14(10)
=31.4 units for the Surface Area

Answer:
Step-by-step explanation:
5x - 17 + 3x - 11 = 180
8x - 28 = 180
8x = 208
x = 26
Heres what you do: Replace X with -3 and Y with 2. Your equation will look like this: 6(-3)-2. Multiply 6 and -3 to get -18. Then subtract 2 from -18. Your answer is -20
