The cylindrical water tank on a semitrailer has a length of 20 feet. The volume of the tank is equal to the product of , the square of the radius of the tank, and the length of the tank. Let V represent the volume of the tank, r represents the radius of the tank, and h represents the length of the tank.

Create an equation that could be used to find the volume, V, of the cylindrical tank.

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
