Formula: A=(pi)r^2
Substitution: A=3.14(7^2)
A=3.14(49)
Solve: A=153.86 in^2
*I personally like to use the pi sign on my calculator to multiply the radius squared by, but my keyboard did not have a pi sign. Usually, the pi sign is more exact. If you used the pi sign, your answer would be 153.94 inches^2. Hope this helps!
Answer:
6.79
Step-by-step explanation:
you just divide 27.16 (the cost) by 4 (how many sandwiches were purchased)
-6
-6i
6i
6
1) √4 . √-3 . √-3
2) √-4 . √-3 . √-3
.
Therefore, - 6i
3) √4 . √3 . √-3
4) √4 . √3 . √3
Therefore, √4 . √3 . √3 = 2 . 3 = 6
Y-4X =3 ; 2x-3y=21
Y= 3+ 4x
2x -3( 3+4x)= 21
2x- 9- 12x= 21
-10x -9= 21
-10x -9+9= 21+9
-10x = 30
X= 30/-10= -3
Y= 3+4x = 3+ 4* (-3)= 3-12= -9
