Answer:
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume of cylinder = πr^2h
Where
π is a constant whose value is 3.14.
r represents the radius of the cylinder.
h represents the height of the cylinder.
From the information given,
The radius of a cylinder is 7.8*10^-4 m.
The height of the cylinder is 3.4*10^-2.
Therefore,
Volume of cylinder =
3.14 × (7.8*10^-4)^2 × 3.4*10^-2
= 3.14 × 60.8*10^-8 × 3.4*10^-2
= 649.52784 × 10^- 10 m^2
The answer would be percent decrease because if it started at 50 and turned to 40, it lowered since we know 50 is higher than 42 so it dropped by 8 since 8 divided by 50 0.16 and 0.16 times 100 EQUALS 16%
