Find the surface area of each figure. Round your answers to the nearest hundredth, if necessary

506π ft^2

Step-by-step explanation:

here's your solution

=> height of cylinder = 12 ft

=> radius of cylinder = 11 ft

=> surface area of cylinder = 2πr(h+r)

=> SA = 2*11(12+11)*π

=> SA = 22*23π

=> SA = 506π ft^2

the 3rd option is right

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
