Try this option, modify design according to local requirements.
Combine the terms. Note that: one positive and one negative sign results in a negative sign.
Simplify: 5 + (-4) = 5 - 4 = 1
1 + (-7) = 1 - 7 = -6
-6 + 2 = -4
-4 is your answer

Answer:
263.76
Step-by-step explanation:
To answer this question, we need to know the equation for surface area of a cylinder which can be given as Surface Area=2*pi*
+2*pi*R*H, where R is the radius of the cylinder (also can be calculated as Diameter/2=6/2=3) and H is the height of the cylinder which is given as 11. Considering pi=3.14, the surface area of the cylinder can now be calculated as 2*3.14*
+2*3.14*3*11=263.76.
1. 92 x 43 = 3,956
2. 524 x 51 = 26,724
3. 294 x 32 = 9,408
4. 828 x 24 = 19,872
