Determine the radius of a sphere with a surface area of 5542m^2.
I think the answer is 2771 but I'm not sure
Almost three thousand meters can't be right.
SA = 4 * 3.14 * r^2
5542m^2 = 12.56r^2
5542 / 12.56 = r^2
441.242 = r^2
21 = r
To determine the radius of a sphere with a given surface area, you can use the formula for the surface area of a sphere in terms of its radius, which is:
Surface Area = 4πr^2
In this case, you are given a surface area of 5542m^2. So, you can set up the equation as follows:
5542 = 4πr^2
To find the radius, you need to isolate it on one side of the equation. Divide both sides of the equation by 4π:
5542 / (4π) = r^2
Now, you can solve for r by taking the square root of both sides:
√(5542 / (4π)) = r
Using a calculator, you can evaluate the right side of the equation to find the radius. The final answer will be the approximate value of the radius of the sphere.
