1. **State the problem:**
We have a cylinder with height 24 feet and radius 2 yards. We need to find:
a) The curved surface area in square feet.
b) The gallons of paint needed if 1 gallon covers 12 ft².
c) The cost to paint the curved surface if paint costs 15.50 per gallon.
2. **Convert units:**
Since height is in feet and radius in yards, convert radius to feet:
$$2 \text{ yards} = 2 \times 3 = 6 \text{ feet}$$
3. **Formula for curved surface area of a cylinder:**
$$\text{Curved Surface Area} = 2 \pi r h$$
where $r$ is radius and $h$ is height.
4. **Calculate curved surface area:**
$$2 \pi \times 6 \times 24 = 288 \pi \approx 288 \times 3.1416 = 904.78 \text{ ft}^2$$
5. **Calculate gallons of paint needed:**
Each gallon covers 12 ft², so gallons needed:
$$\frac{904.78}{12} \approx 75.40 \text{ gallons}$$
6. **Calculate cost of paint:**
Cost per gallon is 15.50, so total cost:
$$75.40 \times 15.50 = 1168.70$$
**Final answers:**
- a) Curved surface area = $904.78$ ft²
- b) Paint needed = $75.40$ gallons
- c) Cost = $1168.70$
