Find the surface area of the following cone.

Round the answer to four decimal places.

A=πr(r+h2+r2)

Step-by-step explanation:

r = 9

h = 6.75

= 572.56

a. -0.3 > -0.33

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.
