Answer:

D. cluster

Step-by-step explanation:

Convenience: Based on availability.

Systematic: The first element is sorted randomly, then the others follow a pattern.

Random: Each member of a sample has the same probability of being sorted.

Cluster: Each group is cluster, and when a cluster is sorted, every member of the group is sample. This is the correct answer.

Stratified: Population is divided into groups and then members from these groups are sorted.

A birthday cake is being made using a cylindrical baking pan. The radius of the pan is 4 inches, and the height is 5 inches.
aleksandr82 [10.1K]

Answer:

the formula represent the correct way is  π(4)^2 (5)

Step-by-step explanation:

The formula that represent the correct way to calculate is given below:

As we know that

Volume = πr^2 h

where

r denotes the radius i.e. 4 inches

And, h denotes the height i.e. 5 inches

Now placed these values to the above formula

So,

= π(4)^2 × 5

= 80π in^3

Hence, the formula represent the correct way is  π(4)^2 (5)
