Question

find the surface area of this cylinder. use 3.14 for π. do not round your answer. what is the area of both circles? both circles: ?cm²

Explanation:

Step1: Identify radius and formula for area of one - circle

The radius of the circle $r = 8$ cm. The formula for the area of a circle is $a=\pi r^{2}$.

Step2: Calculate area of one - circle

Substitute $r = 8$ cm and $\pi=3.14$ into the formula: $a = 3.14\times8^{2}=3.14\times64 = 200.96$ $cm^{2}$.

Step3: Calculate area of both circles

Since there are two circular bases in a cylinder, the area of both circles is $2\times a$. So, $2\times200.96 = 401.92$ $cm^{2}$.

Answer:

$401.92$
