Question

Select all the pairs that could be a reasonable approximation for the diameter and the circumference of a circle explain your reasoning

Answer 1

Answer:

The answer is "19 inches and 60 inches".

Step-by-step explanation:

Throughout this question, the choices were missing that's why its correct solution can be defined as follows:

The formula for diameter= $d=2r$ 

The formula for circumference = $C=2\pi r$  

let the r=9.5 so, the diameter and the circumference are:

$\to d= 2 r= 2\times 9.5 =19\\\\\to C= 2 \pi r= 2\times \frac{22}{7} \times 9.5 =59.71 \approx 60$
