Formula for the surface area of a cylinder: 2 x pi x r^2 + 2 x pi x r x h
Radius (r) = 3
Height (h) = 3
2 x pi x 3^2 + 2 x pi x 3 x 3
2 x pi x 9 + 2 x pi x 9
18pi + 18pi
36pi = 113.1 cm^2

Answer:
33.33%
Step-by-step explanation:
Formula for calculating Percentage change =
<u>New Price - Old Price</u> x <u>100</u>
Old Price 1
Where new price is $8
Old Price is $6
Step 2: Input the variables in the above formula
<u>$8 - $6</u> x <u>100</u>
$6 1
= <u>$2</u> x 100
$6
= $0.333 x 100 = 33.33%
Percentage change = 33.33%
