The faces of triangular pyramid have a base of 5cm and a height of 11cm what is the lateral area of the pyramid

55cm

Step-by-step explanation:

11 x 5 = 55, so the area of the pyrmid is 55cm.

You will have to multiply 55 x 5 because if the base if 5 cm and the height is 11 cm which equals to 55 and a pyramid has 5 faces, so the answer will be 220. I hoped this helped! :)

Step-by-step explanation:

it could be 1,3 and more others to create a cylinder.

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
