Multiply (or distribute) the exponent outside the parenthesis with every exponent inside the parenthesis, remember that if there is no exponent shown, then the exponent is 1.

Convenient: Sample drawn from a conveniently available pool.

Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.

Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.

Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.

In this question:

People divided into groups, by households.

dmitriy555 [2]

Answer:

<h2>C) 132 sq. cm</h2>

Step-by-step explanation:

We must calculate the lateral area of a cylinder.

The formula is:

A=2\pi rH

r - radius

H - height

We have H = 6 cm and r = 3.5.

Substitute:

A=2\pi(3.5)(6)=42\pi\ cm^2

Use \pi\approx\dfrac{22}{7}

A\approx42\left(\dfrac{22}{7}\right)=(6)(22)=132\ cm^2
