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
A=10
b=2
i got my answer by doing 4*2*2*2 which is 12
65,000=6.5*10^4
In scientific notation
Hey there!
Formula for the area of a circle: 
Formula for the radius of a circle: 
First, let's divide the diameter by 2 in order to find the radius.
16/2 = 8
Next, we'll plug our values into the formula (found above).
A = pi x 8^2
A = pi x 64
A = 64pi^2 or A = 201.1cm^2
Hope this helps!! :)
