Which function has a greater rate of change

A has a rate of change of -5 and is greater than Bs -4.5

step-by-step explanation:

the base of the pyramid has a square base with an edge length of 2 cm, thus a right triangle is formed by half of the length of the base, the height of the pyramid and the slant height.

therefore, using the trigonometry, we have

⇒

⇒

now volume of the pyramid is given by:

v= where ab is the area of the base and h is the height.

v=

v=

since, the answer is close to , therefore option b is correct.
