Question

find the surface area of this cylinder. use 3.14 for π. 5 cm 4 cm surface area of a cylinder la = 2πrh sa = la + 2b sa = ? cm² round your answer to the nearest tenth

Explanation:

Answer:

First, find the lateral area (LA):
\( LA = 2\pi rh = 2 \times 3.14 \times 5 \times 4 = 125.6 \)

Then, find the area of the base (B). The base is a circle, so \( B = \pi r^2 = 3.14 \times 5^2 = 78.5 \)

Now, find the surface area (SA):
\( SA = LA + 2B = 125.6 + 2 \times 78.5 = 125.6 + 157 = 282.6 \)

So the surface area is \( 282.6 \) \( \text{cm}^2 \)
