Question

A toy ball can be modeled as a sphere. Eva measures its diameter as 15.7 cm. Find the

ball's volume in cubic centimeters. Round your answer to the nearest tenth if necessary

Answer 1

Answer: is 2026.3 cm ^3

Explanation:

Answer 2

`v = 2064.2 {cm}^(3)`

Explanation:

we first consider the formula for the volume of a sphere

`v = (4)/(3) \pi {r}^(3)`

we were given diameter of 15.7cm.

we can find the radius by dividing the diameter by 2

because two times a radius makes a diameter.

`(15.7)/(2) = 7.9cm`

we have the radius as 7.9cm.

and we know pi (π) to be 3.14 or 22/7.

but in this case, we use 3.14.

now let's substitute the values in the formula

`v = (4)/(3) * 3.14 * {7.9}^(3)`

and we will get

`v = 2064.19 {cm}^(3)`

but the nearest 10th will be

`v = 2064.2 {cm}^(3)`
