Answer:
28.27 ft²
Step-by-step explanation:
where 
is the radius
Plug in 3 for the radius
(approximate answer when rounded to the nearest hundredth)
Therefore, the area of the circle is 28.27 ft².
I hope this helps!
Answer: Yes.
Step-by-step explanation: If a number ends in 0, 2, 4, 6, or 8, the number even number.
F ( x ) = ( x + 7 ) ( x + 4 ) - ( x + 5 ) ( x + 2 ) =
= ( x² + 4 x + 7 x + 28 ) - ( x² + 2 x + 5 x + 10 ) =
= ( x² + 11 x + 28 ) - ( x² + 7 x + 10 ) =
= x² + 11 x + 28 - x² - 7 x - 10 = 4 x + 18
Answer:
The area of the shaded region is 4 x + 18.
Answer:
60 square feet
Step-by-step explanation:
to get the square feet (or the area basically) you multiply the length and width together
FIRST METHOD
From the frequency table, X stands for the number and F stands for the number of time that a particular number occur.
So, if we break the table down, we are going to have the following numbers:
1, 1, 2, 2, 3, 3, 3, 3, 3, 4.
The total number of occurrence = Addition of F = 10
Mean = [Summation of all occurrence] / Number of occurrence
Mean = [1+1+2+ 2+3 +3 +3 +3 +3 + 4] / 10 = 25 /10 = 2.5
Therefore, mean = 2.5
SECOND METHOD
Mean = [ 1*2] + [2* 2] + [3 * 5] + [4*1] / [2+ 2 + 5+ 1]
Mean = 2 + 4 + 15 + 4 / 10 = 25 / 10 2.5
Therefore, Mean = 2.5
