The formula for the volume of a right square pyramid is given below, where a is the side length of the base and h is the height. rewrite the formula by solving for a. v= 1/3 a^2h

a = √(3V/h)

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Step 1: Define

V = 1/3a²h

Step 2: Solve for a

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
