To find the surface area of a cylinder, you need to find the sum of the areas of the two bases and the lateral surface area.
The formula for the surface area of a cylinder is:
Surface Area = 2πr^2 + 2πrh
Where r is the radius of the base and h is the height of the cylinder.
Since the problem does not provide the values of r and h, we cannot calculate the exact surface area. However, we can use the given approximation of pi (3.14) and the dimensions of the cylinder to find an approximate value.
Without knowing the dimensions of the cylinder, we cannot determine the correct answer among the options provided.

To find the surface area of a cylinder, we need to know its height and radius. The formula for the surface area of a cylinder is:
Surface Area = 2πr(r + h)
where π is approximately 3.14, r is the radius, and h is the height of the cylinder.
To find the surface area, we need to substitute the given values into the formula. However, since you haven't provided the values of the radius and height, I cannot calculate the surface area for you.
To find the surface area of the cylinder, we need to calculate the sum of the areas of the two bases and the lateral surface area.
First, let's calculate the radius of the base. The diameter is given as 7 yards, so the radius (r) is half of that, which is 7/2 = 3.5 yards.
Next, let's calculate the area of each base using the formula A = πr^2. Substituting the radius value, we get:
A = 3.14 * (3.5)^2
A ≈ 38.465 square yards
Since there are two bases, the total area contributed by the bases is 2 * 38.465 = 76.93 square yards.
Finally, let's calculate the lateral surface area using the formula A = 2πrh. Substituting the radius (3.5) and height (8), we get:
A = 2 * 3.14 * 3.5 * 8
A ≈ 219.968 square yards
The total surface area is the sum of the areas of the bases and the lateral surface area: 76.93 + 219.968 ≈ 296.898 square yards.
None of the given options matches this value, so there is a mistake in the options provided.
