Answer:</h3>
The Area of the tray ≈380 cm
<h3>
Solution:</h3>
- We are given the diameter of the tray, which is equivalent to 22 cm.
- We are asked to find the area of the tray.
- Remember the formula:
- Area of a circle = πr²
- Where
- π -> pi (3.14...)
- r -> radius
- Notice that we aren't given the radius. We're given the diameter only.
- No reason to panic. We can easily find the radius by dividing the diameter by 2.
- The radius is equal to 11 cm.
- Now, plug the values into the formula:
- A=π(11)²
- A=121π
- A≈380 cm
Hope it helps.

A graphing calculator is just easier to graph the points than having to put every point on a piece of graph paper. the calculator also can tell you a bunch of other things like the domain or range or y intercept or x intercept. it’s just all along easier

It is found that Margo will be using random sampling.
• Random sampling in statistics is a part of the sampling technique in which each sample has an equal probability of being chosen. In other words, a sample chosen randomly is an unbiased representation of the total population.
Sample strategies may be classified as :
1) Convenient : The sample which is drawn from a conveniently available pool.
2) Random : When all options are into a hat and draw some of team
3) Systematic : Every kth element
4) Cluster : When we divide population into groups called clusters, and each element os cluster is surveyed.
5) Stratified : In stratified also divides the population into groups, However only some of the elements of the group are surveyed.
According to the question
Marbles are taken from the bag, and after they are taken they are again placed back in the bag so it depicts Random Sampling.
