Answer:
Step-by-step explanation:
First you have to find the area of the full circle.
Area of circle:
A = pi radius^2.
A = 4 x 4
A = 16 pi squared
Area of rectangle:
3 x 3 = 9 cm
Now you have to subtract.
16 - 9 = 7 pi spuared
or if you answer wants to go a step farther:
21.98 squared
Let the number sold of veggie pizza be a
The number sold of cheese pizza be b
a+b=25…1
A+7=b…2
Sub 2 into 1
a + a+7 = 25
2a+7=25
2a=18
a=9
Sub a=9 into 2
9+7=b
b=16
They sold 9 veggie pizza and 16 cheese pizza
