Question

If an orbiting satellite has a diameter of 60 cm, what is the total surface area of the satellite? (HINT: surface area = 4ℼr²)

Answer 1

Answer:

SA = 3,600π cm²

Step-by-step explanation:

You are given the formula, and the diameter.  The formula uses radius, which is 1/2 of the diameter.  In this case, r = 30.  Plug that into the formula and simplify...

SA = 4π(30²)

   SA = 4π(900)

       SA = 3,600π
