Im literally almost done can someone pls tell me what the surface area formula is for this figure i've missed this time and time again

Step-by-step explanation:

Each circle is pi*r*r (pi r squared)

So 2*pi*r*r

The top of the rectangle if just the circumference of the circle = 2*pi*r

So the area of the rectangle is 2*pi*r*h

So the total area =2*pi*r*r+2*pi*r*h

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

8
