To find the surface area of a cylinder, you need to sum the areas of the two bases and the lateral surface area.
The formula for the surface area of a cylinder is: SA = 2πr² + 2πrh
Assuming the given options refer to the surface area in square centimeters (sq cm), I will use this unit throughout the calculation.
Let's assume the cylinder has a radius of r and a height of h. To find the surface area, we need to know the values of r and h.
Since the given information about the cylinder is missing, it is not possible to determine the exact surface area. Therefore, none of the given options are correct.

Find the surface area of the cylinder with a height of 15cm and radius of 5cm below. Use the approximate 3.14 fo pi
A;1099 sq cm
B;535.8 sq sm
C;628 sq cm
D;628 cm

D;628 cm
To find the surface area of the cylinder, we will use the formula: SA = 2πr² + 2πrh.
Given the height (h) as 15 cm and the radius (r) as 5 cm, we can substitute these values into the formula:
SA = 2π(5)² + 2π(5)(15)
= 2π(25) + 2π(75)
= 50π + 150π
= 200π
Using the approximate value of π as 3.14, we can now evaluate the surface area:
SA ≈ 200(3.14)
≈ 628 cm²
Therefore, the correct answer is C; 628 sq cm.
Given the height (h) as 15 cm and the radius (r) as 5 cm, we can substitute these values into the formula:
SA = 2π(5)² + 2π(5)(15)
= 2π(25) + 2π(75)
= 50π + 150π
= 200π
Using the approximate value of π as 3.14, we can now evaluate the surface area:
SA ≈ 200(3.14)
≈ 628 cm²
Therefore, the correct answer is C; 628 sq cm.
