Question

The surface area of a sphere is 7.84 high put to the power to what is the radius of the sphere

Answer 1

To find the radius of a sphere given its surface area, we can use the formula for the surface area of a sphere:

Surface Area = 4πr^2

where "r" is the radius of the sphere.

In this case, the surface area is known to be 7.84 (given in the question). Therefore, we can set up the equation:

7.84 = 4πr^2

To isolate "r", we divide both sides of the equation by 4π:

7.84 / (4π) = r^2

Simplifying further:

1.97 / π = r^2

To find the radius, we take the square root of both sides:

√(1.97 / π) = r

This expression gives us the value for the radius of the sphere.
