Pi = 3.14

2*3.14 = 6.28
4*3.14 = 12.56

area = pi [ C/ (2pi)] ^2
C= circumference

area of small = 3.14 (6.28/6.28)^2 =3.14
area of regular = 3.14 (12.56/6.28)^2 = 12.56

12.56/3.14 = 4 

The regular pancake is 4 times the area.

Answer:

a1= -19, a2= 9

Step-by-step explanation:

step 1. Add 5 + 9 /a +5/ = 9+5

step 2. Use the absolute value definition, rewrite the absolute value equation as two separate equations. a+5=14 a+5= -14

step 3. a=9 a+5= -14

step 4. a= 9 a= -19 the equation has 2 solutions

a¹ = - 19, a²= 9

1. 2 |-9| <br> 2. 4 |-4| <br> 3. 1 |1| <br> 4. 11 |11| <br> 5. 9 |-2|
Zielflug [23.3K]

The absolute value is the distance the number is from zero. For example, the absolute value of -4 is 4 and the absolute value of 4 is 4. Also |-24| is 24.

The absolute value of -9 is 9. 2 times 9 is 18.

The absolute value of -4 is 4. 4 times 4 is 16.

The absolute value of 1 is 1. 1 times 1 is 1.

The absolute value of 1 is 11. 11 times 11 is 121.

The absolute value of -2 is 2. 9 times 2 is 18.

  ━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

The opposite of a number is the difference it is from zero but on the other side (opposite sign). For example, the opposite of -5 is 5, and the opposite of 2 is -2.

11 is opposite of -11.

-8 is opposite of 8.

31 is opposite of -31.

-1 is opposite of 1.

-17 is opposite of 17.

♡ Hope this helped! ♡
