The diameter of a round dinner plate is 10 inches. What is the area of the plate? A. 314 square inches
B. 39.25 square inches
C. 39.25 inches
D. 78.5 square inches
Answers
The area of table is 78.5 square inches.
What is area?
A figure's area is the amount of space it takes up in two dimensions. To put it another way, it is the number that tells how many unit squares cover the surface of a closed figure. Square units, such as square inches, square feet, and so on, are the standard measurement for area.
Given the diameter of dinner plate = 10 inches
shape of plate is circular
area of circle is πr²
where r is radius
r = d/2 = 10/2 = 5 inches
A = πr²
A = 3.14(5)²
A = 3.14 x 25
A = 78.5 square inches
Hence area is 78.5 square inches.

Since the diameter is 10 inches, the radius must be half of that: 10/2=5.
A=π(5)ˆ2
A=25π
A=25π or 78.54 inches

Rearrange on same sides
-17 - 7 = 9x - 3x
-24 = 6x
Divide by 6 on either sides to isolate 6
6 and 6 cancels out
-4 = x

B. Removing the outlier will not change the variance of the data set.
C. Removing the outlier will increase the variance of the data set.
D. Removing the outlier will decrease the spread of the graph of the data set.
Answers
Answer:
D.
Step-by-step explanation:
if you remove the low value outlier, the variation from the mean will decrease therefore decreasing the varianc.
Answer:
D. Removing the outlier will decrease the spread of the graph of the data set.
Step-by-step explanation:
Outliers increase the spread of the data set.
So removing an outlier will generally decrease the spread or variance or standard deviation of a data set.
The answer is
D. Removing the outlier will decrease the spread of the graph of the data set.
