The height of one metallic cylindrical rod is 6 centimeters and its radius is 3 centimeters. The height of a second metallic cylindrical rod is 18 centimeters and its radius is 3 centimeters. What is the ratio of the volume of the second cylinder to the volume of the first cylinder

The ratio of the volume of the second cylinder to the volume of the first cylinder is 3 : 1

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant

Considering the metallic cylindrical rod,

Radius = 3 cm

Height = 6 cm

Volume = π × 3² × 6 = 54π cm³

Considering the second metallic cylindrical rod,

Radius = 3 cm

Height = 18 cm

Volume = π × 3² × 18 = 162π cm³

The ratio of the volume of the second cylinder to the volume of the first cylinder is

162π/54π = 3/1

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
