A circle has a circumference of
32. What is the circumference of
a bigger circle if the scale factor
4:7?

The circumference of the bigger circle is 56.

Step-by-step explanation:

Step 1:

The circumference of a circle is given by twice the product of π and its radius r.

The circumference of a circle =

The scale factor is 4: 7, so the circumference too will be of ratio 4: 7.

Step 2:

We equate the ratios to each other to find the value of circumference for the bigger circle.

4: 7 is equal to 32: x, assume x is the circumference of the bigger circle.

We divide the ratios as such;

So the circumference of the bigger circle is 56.

astronomers is your final answer! : )
