The surface area of a sphere is 7.84 piece squared what is the radius of the sphere
First, let's use the formula for the surface area of a sphere:
Surface Area = 4πr^2
We are given that the surface area is 7.84, so we can set up the equation:
7.84 = 4πr^2
To solve for the radius (r), we can divide both sides of the equation by 4π:
7.84 / (4π) = r^2
Now, we can simplify the expression on the left side:
7.84 / (4π) = r^2
0.62 / π = r^2
To find the value of r, we can take the square root of both sides:
√(0.62 / π) = r
Using a calculator, we find:
r ≈ 0.498
So, the radius of the sphere is approximately 0.498 units.
