Answer:

Step-by-step explanation:

There is no solution as you have two variables and only one equation. The best you can do is solve for one variable as a function of the other.

$7x^2+11y^2=40\\ \\ 11y^2=40-7x^2\\ \\ y^2=\frac{40-7x^2}{11}\\ \\ y=\sqrt{\frac{40-7x^2}{11}}$

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

grin007 [14]

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

Answer:

200 rounded to the nearest hundredth

Step-by-step explanation:
