Find the approximate surface-area-to-volume ratio of a bowling ball with a radius of 5 inches. a. 0.6 b. 0.67 c. 1.67 d. 25

A

Step-by-step explanation:

Bowling ball is in the shape of a sphere. So, we need the formula for surface area and volume of a sphere.

Surface Area of Sphere =

Volume of Sphere =

Ratio of Surface Area to Volume =

Let's simplify this and put r = 5 in it to get the answer.

Thus, the correct answer is A.

option A

Step-by-step explanation:

To solve this exercise you must apply the formula for calculate the surface area of a sphere, which is shown below:

Where r is the radius of the sphere.

And the formula of the volum of a sphere is:

By definition, the surface area to volume ratio of a sphere is equals to:

Substituting, you obtain:

1e+27

step-by-step explanation:

it would be 6xy and -16xy.
