1 - Convert the percentage to a decimal.
2 - Multiply the decimal by the number you are finding the percentage of. This will be your final answer.

(1) 20% of 80
20 / 100 = 0.20
20% = 0.20
0.20 * 80 = 16
16 is 20% of 80

(2) 55% of 1000
55 / 100 = 0.55
55% = 0.55
0.55 * 1000 = 550
550 is 55% of 1000

(20/100)*80=16(20%)
(55/100)*1000=550(55%)

The volume of a cylinder is given by πr²h where, r is the radius of the cylinder and h is the height of the cylinder. Also r=d/2 , where d is the diameter of the cylinder. Therefore the volume becomes one-fourth of the initial volume. ... The new volume is 730 mL.
