The answer choices are 3π 9π 12π 36π

easy, 9pi since area is R^2*PI

Step-by-step explanation:

One pecan cheese cake costs $8, One Strawberry cheesecake costs $19.75

Step-by-step explanation:

8p + 12s = 296

1p + 4s = 87

1p + 4s = 87 is multiplied until one of the pieces equals 8 or 12

1 x 8 = 8     4 x 8 = 32     87 x 8 = 696

now we subtract

8p + 32s = 696

-  8p + 12s = 296

20s = 400

s = 20

Now we plug it into one of the original equations

8p + 12(20) = 296

8p + 240 = 296

296 - 240 = 56

8p = 56

56 / 8 = 7

p = 7

I understand that the first part doesn't make any since, but when you put them both into the equation the exact answer is $19.75
