To find the surface area of a cylinder, you need to add the areas of the two bases and the lateral surface.
The formula for the lateral surface area of a cylinder is:
Lateral Surface Area = 2πrh
The formula for the area of the base of a cylinder is:
Base Area = πr^2
Since the bases are the same, you multiply the base area by 2 to get the total area of the bases.
So, the surface area of the cylinder is:
Surface Area = 2(πr^2) + 2πrh
Since the value of pi is given as 3.14, you can substitute these values into the formula to calculate the surface area.
However, you have not provided the measurements of the radius (r) and height (h) of the cylinder. Without this information, the surface area cannot be calculated.
Find the surface area of the cylinder. Use the approximation 3.14 for pi.

7 and 8 yd
Given the radius (r) of 7 yards and height (h) of 8 yards, we can calculate the surface area of the cylinder using the formula:
Surface Area = 2(πr^2) + 2πrh
Substituting the given values:
Surface Area = 2(3.14)(7^2) + 2(3.14)(7)(8)
Surface Area = 2(3.14)(49) + 2(3.14)(7)(8)
Surface Area = 2(153.86) + 2(175.84)
Surface Area = 307.72 + 351.68
Surface Area ≈ 659.4 square yards
Therefore, the approximate surface area of the cylinder is 659.4 square yards.
Surface Area = 2(πr^2) + 2πrh
Substituting the given values:
Surface Area = 2(3.14)(7^2) + 2(3.14)(7)(8)
Surface Area = 2(3.14)(49) + 2(3.14)(7)(8)
Surface Area = 2(153.86) + 2(175.84)
Surface Area = 307.72 + 351.68
Surface Area ≈ 659.4 square yards
Therefore, the approximate surface area of the cylinder is 659.4 square yards.
