Question

Karen had a garden that is 30 feet by 25 feet. If she plans to put in a fire pit that has a diameter of 12 feet how much yard space will she still have?

Answer 1

636.9 square feet

Explanation:

So first you need to find the area of her garden, in square feet. 30×25=750

Then, you need to find the area of the fire pit. Since the fire pit is described as having a diameter, we can assume it's a circle. The formula for an area of a circle is A=πr², so I'll use 3.14 for pi (The radius of a circle is half it's diameter).

A=πr²

A=3.14(6)²

A=113.1

Now that both areas are solved, you can simply subtract the area of the fire pit from the area of the garden. 750-113.1=636.9

She will have 636.9 square feet of space left in her garden.
