Question

the surface area of a cylinder = 2πr² + 2πrh. use 3.14 for π. what is the surface area of this cylinder? you may use the calculator tool in the menu. surface area =? yd² height = 9 yd radius = 8 yd

Explanation:

Step1: Calculate base - area part

$2\times3.14\times8^{2}=2\times3.14\times64 = 401.92$

Step2: Calculate lateral - area part

$2\times3.14\times8\times9=452.16$

Step3: Calculate total surface area

$401.92 + 452.16=854.08$

Answer:

$854.08$
