Stephanie is cutting a pie. Stephanie's mother wants one fourth of the pie. The diameter is 20 cm.
What is the sector area of the pie her mother does not want?

Answers

Answer:

78.55cm^2

Step-by-step explanation:

Given data

DIameter of pie= 20 cm

Radius of pie= 10cm

Area of pie= πr^2

Area= 3.142*10^2

Area= 3.142*100

Area= 314.2 cm^2

Hence one fourth of 314.2 cm^2 is

= 314.2/4

= 78.55cm^2

Therefore the area of the sector is 78.55cm^2

Answers

Answer:

38.6 units.

Step-by-step explanation:

The given figure is composed of a parallelogram and one semicircle.

We need to find the perimeter of the parallelogram.

Perimeter = sum of all sides

ATQ,

P = 9+8+9+(2πr/2)

i.e.

[tex]P=26+\pi r\\\\=26+3.14\times 4\\\\=38.56\ \text{unit}[/tex]

= 38.6 units

So, the perimeter of the figure is equal to 38.6 units.

In each of the four questions, he was able to eliminate two answers as being clearly wrong and was left with three answer choices to choose from. In each of the four questions, he randomly selected one of the remaining three answers. Which of these statements describes how Ahmed could simulate this situation with a random number generator to determine if he will select the correct answers for these four questions? It is impossible to simulate this with a random number generator without knowing what the correct answer choices were Using his calculator, Ahmed could use the Randint(1,4) command three times to select three integers from 1 to 4. Let a 1 indicate a correct guess, and a 2, 3, or 4 indicate an incorrect guess. Count the number of 1s to correspond to the number of correct guesses. Using his calculator, Ahmed could use the Randint(1,4) command to select a random integer from 1 to 4. This would be the number of correct guesses he made on the four questions. Using his calculator, Ahmed could use the Randint(1,3) command four times to select four integers from 1 to 3. Leta 1 indicate a correct guess, and a 2 or 3 indicate an incorrect guess.
