To find the surface area of a cylinder, we need to find the sum of the areas of the two circular bases and the lateral surface area.
The formula for the surface area of a cylinder is given by:
Surface Area = 2πr(r + h)
Given that the approximation for pi is 3.14, we need to calculate the values of r and h.
Please provide the values of the radius (r) and height (h) of the cylinder to proceed with the calculation.
Height:8 Diameter:7
To find the surface area of the cylinder, we need to first find the radius of the circular base using the diameter.
The radius (r) is half the value of the diameter, so:
r = 7/2 = 3.5
The height (h) is given as 8.
Now we can substitute the values into the formula for surface area:
Surface Area = 2πr(r + h)
= 2 * 3.14 * 3.5(3.5 + 8)
= 2 * 3.14 * 3.5 * 11.5
≈ 577.76 square yards
Therefore, the surface area of the cylinder is approximately 577.76 square yards.

Apologies for the incorrect calculation. Let's recalculate the surface area of the cylinder with the correct values.
Given that the height (h) is 8 and the radius (r) is half the diameter of 7, we have:
r = 7/2 = 3.5
h = 8
Substituting these values into the formula for surface area:
Surface Area = 2πr(r + h)
= 2 * 3.14 * 3.5(3.5 + 8)
= 2 * 3.14 * 3.5 * 11.5
≈ 329.7 square yards
Therefore, the surface area of the cylinder is approximately 329.7 square yards.

Apologies for the mistake in the previous response. Let's recalculate the surface area with the correct values.
Given that the height (h) is 8 and the radius (r) is half the diameter of 7, we have:
r = 7/2 = 3.5
h = 8
Substituting these values into the formula for surface area:
Surface Area = 2πr(r + h)
= 2 * 3.14 * 3.5(3.5 + 8)
= 2 * 3.14 * 3.5 * 11.5
≈ 252.77 square yards
Therefore, the surface area of the cylinder is approximately 252.77 square yards.
