Answer 1

Answer:

It will cost $427.04 to paint deck and it will cost 958.485 to add fencing around deck

Step-by-step explanation:

Diameter of swimming pool = 27 feet

Radius of pool r=$\frac{27}{2}=13.5 feet$

Surrounding the pool is a  deck that extends 5 feet from the edges of the pool

Outer radius R = 13.5+5=18.5

Area of deck = Outer area - Inner area

Area of deck =$\pi R^2 -\pi r^2$

Area of deck = $3.14(18.5^2-13.5^2)$

Area of deck = $502.4 ft^2$

Cost of painting 1 sq.feet = $0.85

Cost of painting 502.4 sq.feet = $502.4 \times 0.85=427.04$

Perimeter of deck = $2 \pi R = 2 \times 3.14 \times 18.5 =116.18 feet$

Cost of fencing 1 foot = $8.25

Cost of fencing 116.18 foot = $116.18 \times 8.25=958.485$

Hence it will cost $427.04 to paint deck and it will cost 958.485 to add fencing around deck
