find the surface area of the cylinder, use the approximation of 3.14 for pi

1 answer

To find the surface area of a cylinder, you can use the formula:

\[ \text{Surface Area} = 2\pi r(h + r) \]

where:

  • \( r \) is the radius,
  • \( h \) is the height, and
  • \( \pi \) is approximately 3.14.

Given:

  • \( r = 2 \) yards,
  • \( h = 3 \) yards.

Now, plug in the values:

\[ \text{Surface Area} = 2 \times 3.14 \times 2 \times (3 + 2) \]

First, calculate \( h + r \):

\[ h + r = 3 + 2 = 5 \]

Now, substitute this back into the formula:

\[ \text{Surface Area} = 2 \times 3.14 \times 2 \times 5 \]

Calculate step-by-step:

  1. \( 2 \times 2 = 4 \)
  2. \( 4 \times 5 = 20 \)
  3. \( 20 \times 3.14 = 62.8 \)

Thus, the surface area of the cylinder is:

\[ \text{Surface Area} = 62.8 \text{ square yards} \]
