I want to build a hot tub and a deck to go around it….the hot tub has a diameter of 12 ft. I want my rectangular deck to go around it and be 20ft by 16 ft. How much wood do i need to buy? (remember I am not putting wood over the tub)

206.9 square feet

Explanation:

We know that the amount of wood purchased has to equal the area of the deck minus the area of the hot tub.

Lets find the area of the hot tub.

Lets make pi equal to 3.141

Now lets find the area of the deck.

Subtract the area of the hot tub from the deck.
