The area of the base is
.. A = πr^2
The lateral area is
.. A = πrh . . . . . where h is the slant height
The total area is
.. π(r^2 +rh) = πr(r +h)

total surface area = 3.14*(5 m)*(5 m +11 m) = 251.2 m²

Measures of central tendency are methods to which an investigator can locate the most central value, or the reoccurring or frequent most value in the set of parameter or statistic. There are three:
Mean. Is the average of the data values
Median. The middlemost value or digit in the data set
Mode. The determining the most frequent parameter To identify which of these three suits the given, arranging them first is a must. Ascending to descending.
Third Period: 0,1,1,1,2,2,2,3,3,3,3 4,4,4,5,8,

The best is mode, why? Because if you observe there is a number most frequent in the data value and it is the fastest way.

Mode = 3

1 3/7 x 2 3/4<br> fraction plz
maksim [4K]

Answer:

\frac{55}{14}

Step-by-step explanation:

First, we convert the mixed numbers into improper fractions: 1\frac{3}{7} =\frac{10}{7}, and 2\frac{3}{4}=\frac{11}{4}. Now, we multiply the fraction using the multiplication rule, \frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}: \frac{10}{7} \times \frac{11}{4} = \frac{110}{28} = \frac{55}{14}.

Thus, the product of the two given fractions is 55/14.

Charlie had a full bottle of water. He drank 1/4 of the water in the morning. He drank 2/5 of the water with lunch. How much of
12345 [234]

Answer:

7/20

Step-by-step explanation:

first of all you have to put the two fractions on the same denominators

1/4 (multiply by 5) and you will get 5/20

2/5(multiply by 4) and you will get 8/20

we have to add 5/20 and 8/20 that gives us 13/20

13/20 is the amount he drank

20/20 - 13/20 =7/20

7/20 is the amount of water left that Charlie has left

Sonja [21]

Answer:

The overall change is -$7.00.

Step-by-step explanation:

If a price goes down $4.25 than it is a negative integer. Same situation if a price goes down $2.75; it is still a negative integer. These two numbers can be expressed as -$4.25 and -$2.75. Finding the overall change causes for adding. Same signs add and keep different signs subtract. -4.25+-2.75=7.00. Therefore, the overall change in price for the two days is -$7.00.
