19. Find the surface area of the cylinder. Use =3.14 and round your answer to the nearest tenth. Formula: SA=2
(3.14)(radius)(height) + (3.14)(radius^2)

To find the surface area of a cylinder, we use the formula: SA = 2 * π * r * h + 2 * π * r^2.
Given that the formula contains the value π (pi) and asks us to round the answer to the nearest tenth, we can assume that π is approximately 3.14.
Let's say the radius of the cylinder is 5 cm and the height is 10 cm.
Plugging these values into the formula:
SA = 2 * 3.14 * 5 cm * 10 cm + 2 * 3.14 * (5 cm)^2
= 314 cm^2 + 2 * 3.14 * 25 cm^2
≈ 314 cm^2 + 157 cm^2
= 471 cm^2
Thus, the surface area of the cylinder is approximately 471 cm^2.
