Answer:
954.56 cm²
Step-by-step explanation:
Firstly i would calculate the circumference of the circles on top of the cylinders:
Circumference of circles = or
d = diameter
r = radius
I will use
circumference = 2 x 3.14 x 8 = 50.24 cm
⇒ This would help me to find out the surface area of the side of the cylinder
50.24 x 11 = 552.64 cm²
⇒ This is the surface are of the sides
Now we have to find the are of the two circles on the top and the bottom:
Area of a circle =
d = diameter
3.14 x 8² = 200.96
⇒ There are two circles so you would times 200.96 by 2
200.96 x 2 = 401.92
Add all the values up:
401.92 + 552.64 = 954.56 cm²
I hope this helps!
