Cassidy is 3 times as old as Drew. In 8 years, Cassidy will only be twice as old as Drew. How old is Cassidy right now? (Thank You for helping!!!)

Cassidy is 24 years old.

Step-by-step explanation:

Cassidy's current age : c=3d

Cassidy's age in 8 years : c+8

Drew's age : d

Drew's age in 8 years : d+8

c+8=2(d+8) and since c=3d then

3d+8=2(d+8)

3d+8=2d+16

d=8

so cassidy's age right now would be 3x8=24.

circumference of the pizza = PI*d

using 3.14 for PI

 circumference = 3.14*18 = 56.52 inches

 56.52 /12 = 4.71 inches of crust
