Question

Elisa wants to use the Fermi process to estimate the number of ping pong balls that would fill a truck. As part of the process, she needs to estimate the volume of a ping pong ball. The diameter of a ping pong ball is about 40 mm. Which estimate best approximates the volume of a ping pong ball?

Answer 1

3 x
`10^(4)`
`mm^(3)`

Step-by-step explanation:

I just took the test

Answer 2

Given:
diameter = 40 mm

Formula:
V = ⁴⁄₃πr³

If π = 3.14, then find the following:
V = ?
r = ?

First, let's calculate radius using this formula: Diameter = 2 × Radius.

r = 40 mm/2
r = 20 mm

Then, we can get volume.

V = ⁴⁄₃(3.14) (20)³
V = ⁴⁄₃(3.14) (8000)
V = 4 (25, 120) / 3
V = 100, 480 / 3
V = 33, 493 mm³
