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 arou

Pachacha [2.7K]

Answer:

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.

$d/2=r\\12/2=6\\\\A=\pi r^{2}\\A=\pi*6^2\\A=36\pi\\$

Lets make pi equal to 3.141

$A=36*3.141\\A=113.076 ft^2$

Now lets find the area of the deck.

$A=l*w\\A=20*16\\A=320 ft^2$

Subtract the area of the hot tub from the deck.

$320-113.076=206.924 ft^2$

I would say that housing availability, inadequate services, pollution and migration from rural areas all present challenges to the regional urban areas but not reduced population. If there is migration to the cities then these above three problems must be dealt with to accommodate the new citizens.
