Question

1. Samantha has a circular shaped pool in her backyard with a diameter of 17 feet. She wants to have a side walk installed around the pool, but needs to know the distance around the outer edge of the pool first. Which expression can Samantha use to determine this distance?

Answer 1

Here, we want to get the expression that correctly represents the distance around the circle, given the diameter of the circle

Mathematically, the distance around the circle is the circumfrence

To calculate the circumfrence, we can use the following formula;

`C\text{ = }\pi d\text{ or 2}\pi r`

With respect to the question, d represents the diameter of which the value is 17

Substituting this into the equation of circumfrence above, we have;

`C\text{ = 17}\pi`
