The surface area of a sphere is 7.84 piece squared what is the radius of the sphere

Answer 1

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.
