Surface area of cylinder has 15 yards radius and 18 yards height caluculate the surface area use 3.14
To calculate the surface area of a cylinder, we need to find the area of the two bases and the area of the lateral surface.
1. Area of base:
The area of a circle is given by the formula A = πr^2, where r is the radius. In this case, the radius is 15 yards, so the area of each base is:
A_base = π(15)^2
A_base = 706.5 square yards
2. Area of lateral surface:
The lateral surface area of a cylinder is given by the formula A = 2πrh, where r is the radius and h is the height. In this case, the height is 18 yards, so the lateral surface area is:
A_lateral = 2(3.14)(15)(18)
A_lateral = 1,017.6 square yards
3. Total surface area:
To find the total surface area, we need to add the areas of the two bases and the lateral surface:
Total surface area = 2(706.5) + 1,017.6
Total surface area = 2,430.6 square yards
Therefore, the surface area of the cylinder with a 15 yards radius and 18 yards height is 2,430.6 square yards.
