To find the surface area of a cylinder, we use the formula:
\[ \text{Surface Area} = 2\pi r(h + r) \]
where:
- \( r \) is the radius of the base of the cylinder,
- \( h \) is the height of the cylinder.
First, we need to find the radius. The diameter of the cylinder is given as 2 yards, so:
\[ r = \frac{\text{diameter}}{2} = \frac{2 , \text{yd}}{2} = 1 , \text{yd} \]
Now we can plug in the values into the surface area formula. The height \( h \) is given as 3 yards. Using \( \pi \approx 3.14 \):
\[ \text{Surface Area} = 2 \times 3.14 \times 1 , \text{yd} \times (3 , \text{yd} + 1 , \text{yd}) \]
Calculating the expression inside the parentheses:
\[ h + r = 3 , \text{yd} + 1 , \text{yd} = 4 , \text{yd} \]
Now substitute this back into the formula:
\[ \text{Surface Area} = 2 \times 3.14 \times 1 , \text{yd} \times 4 , \text{yd} \]
Now calculate the surface area:
\[ \text{Surface Area} = 2 \times 3.14 \times 4 , \text{yd}^2 \]
Calculating:
\[ 2 \times 3.14 = 6.28 \]
\[ 6.28 \times 4 = 25.12 \]
Thus, the surface area of the cylinder is:
\[ \text{Surface Area} \approx 25.12 , \text{yd}^2 \]
So the surface area of the cylinder is approximately 25.12 square yards.
