D. 647 m2; 7411 m3

option A

Step-by-step explanation:

surface area of a cylinder formula:

2pi*r^2+2*pi*r*h

r=radius(3)

h=height(8)

hence,

2*pi*9+2*pi*3*8

so

18pi+48pi=66pi

surface area=66pi

now volume of cylinder formula:

pi*r^2*h

so

pi*9*8

72pi is the height

hence 66pi m^2 is surface area and 72pi m^3 is volume

Hope this helps!

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
