If A varies directly with z, and A is 30 and z is 5, then when z is 1, A is 6.
z: 5 ÷ 5 = 1
A: 30 ÷ 5 = 6
Then, when z is 1, A is 6
So, when z is 9, A is...
z: 1 × 9 = 9
A: 6 × 9 = 54
A is 54
The answer to the question is b
Calculate the circumference of the full circle:
circumference = PI x diameter = 3.14 x 20 = 62.8 inches
the arc length is 160 degrees of the full circle
divide 160 by 360 (full circle) and multiply by the circumference:
160/360 x 62.8 = 27.9 inches
Hey there!
First, you would need to find the area of the circle/pizza . . .
Formula of finding area → pi*r² (Pi * the radius of the circle/pizza²)
---
Once you have found the area, you would need to divide the result by the number 12 since there is a total of 12 slices in the pizza.
---
This is how you would find the area of one slice of pizza.
