Chapter 1, Problem 1.72QP

Interpretation Introduction

Interpretation: The number of basketballs which will take to circle around the equator with the basketballs touching one another has to be calculated and round off the answer to an integer with three significant figures using the given data.

Concept Introduction:

Circumference of the circle:

$\begin{array}{l}\text{Circumference}\text{=}\text{2πr}\\ \text{r}\text{-}\text{radius}\text{of}\text{the}\text{circle}\end{array}$

The diameter of the circle can be calculated by using the below equation.

$\begin{array}{c}\text{d}\text{=}\text{2r}\\ \text{r}\text{-}\text{radius}\text{of}\text{the}\text{circle}\end{array}$
