Area of circle = πr²

= 22/7 × 4²

= 22/7 × 16

= 352/7

= 50.28 ( approx )

Hence, the area of circle is 50.28 feet²

A land owner is planning to build a fenced-in, rectangular patio behind his garage, using his garage as one of the "walls." He
Vitek1552 [10]

Answer:

Maximum area = 800 square feet.

Step-by-step explanation:

In the figure attached,

Rectangle is showing width = x ft and the side towards garage is not to be fenced.

Length of the fence has been given as 80 ft.

Therefore, length of the fence = Sum of all three sides of the rectangle to be fenced

80 = x + x + y

80 = 2x + y

y = (80 - 2x)

Now area of the rectangle A = xy

Or function that represents the area of the rectangle is,

A(x) = x(80 - 2x)

A(x) = 80x - 2x²

To find the maximum area we will take the derivative of the function with respect to x and equate it to zero.

A'(x)=\frac{d}{dx}(80x-2x^{2})

             = 80 - 4x

A'(x) = 80 - 4x = 0

4x = 80

x = \frac{80}{4}

x = 20

Therefore, for x = 20 ft area of the rectangular patio will be maximum.

A(20) = 80×(20) - 2×(20)²

         = 1600 - 800

         = 800 square feet

Maximum area of the patio is 800 square feet.

The following relative frequency table shows reasons given by high school students for their last absence from school.
Yuliya22 [10]

Answer:

The statement which not supported by the relative frequency table is " The reason given the least number of times was did not finish assignment " ⇒ C

Step-by-step explanation:

A relative frequency table shows the mode of a certain type of data based on the population sampled

To find the relative frequency, divide the frequency by the total number of data values

The table:

→  Reason                               :    Relative Frequency

→  Illness                                 :    0.57

→  Overslept                           :    0.20

→  College visit                       :    0.16

→ Did not finish assignment  :    0.07

Lets check each statement

A. More than half the students were absent because of illness

From the table illness is 0.57 which equals to 57% of the students, so more than 50% (half) of the students were absent because of illness

The answer supported by the table

B.  More than one-third of the students were absent because of oversleeping or college visits

From the table overslept is 0.20 and collage visit is 0.16, or means add the two numbers, so 0.20 + 0.16 = 0.36 which equals to 36% and one-third of the students means 33%, so more than one-third of the students were absent because of oversleeping or college visits

The answer supported by the table

C. The reason given the least number of times was did not finish assignment

There is no any reason on the table for the least number of times was did not finish assignment

The answer NOT supported by the table

D. Only 7 students were absent because they did not finish an assignment.

From the table 0.07 Did not finish assignment, that means if the total number of students is 100, than 7 students only did not finish an assignment

The answer supported by the table

E. Less than one-fourth of the students were absent because they overslept

One-fourth means 0.25, and from the table 0.20 over slept, so less than 0.25 of the students were absent because of Overslept

The answer supported by the table
