Question

magnifying glass 5.2 cm 16 cm car tire 23 in 71.6 in part b complete the statements to explain how you found the values in the table. the given diameters are multiplied by constant of proportionality to find the missing circumferences. the given circumferences are select choice by constant of proportionality to find the missing diameters.

Explanation:

The formula for the circumference of a circle is \(C = \pi d\), where \(C\) is the circumference and \(d\) is the diameter. When we know the diameter \(d\) and want to find the circumference \(C\), we use the operation of multiplication (\(C=\pi\times d\)). When we know the circumference \(C\) and want to find the diameter \(d\), we use the operation of division (\(d = C\div\pi\)).

Answer:

The given diameters are multiplied by the constant of proportionality (\(\pi\approx3.14\)) to find the missing circumferences. The given circumferences are divided by the constant of proportionality (\(\pi\approx3.14\)) to find the missing diameters.
