Question

a standard golf ball has a diameter of 1.68 inches. the material used to make the golf ball weighs .6523 ounces per cubic inch. what is the weight, to the nearest hundredth of an ounce, of one golf ball?

Answer 1

Given:

Given that the standard golf ball has a diameter of 1.68 inches.

Radius of the golf ball is 0.84 inches.

The material used to make the golf ball weighs 0.6523 ounces per cubic inch.

We need to determine the weight of one golf ball.

Volume of the golf ball:

The volume of the golf ball can be determined using the formula,

`V=(4)/(3) \pi r^3`

Substituting r = 0.84, we get;

`V=(4)/(3) (3.14)(0.84)^3`

`V=2.481\ in^3`

Thus, the volume of one golf ball is 2.481 cubic inches.

Weight of one golf ball:

The weight of one golf ball can be determined by multiplying the volume of the golf ball with 0.6523 ounces per cubic inch.

Thus, we have;

`Weight=2.481 * 0.6523`

`Weight = 1.62`

Thus, the weight of one golf ball is 1.62 ounces.
