Area of pizza = pi × r^2
pi × r^2 = 220 Sq. cm
22/7 × r^2 =220
r^2 = 220 × 7/22
r^2 = 70
r = square root of 70
r = 8.36
therefore , radius of the pizza is 8.36 cm

First we define the varible to use:
x = represent the number of cookies
Cameron:
The amount of cookies he made was:
x
Deyonne:
We can rewrite the amount in different ways:
x + 0.25x
1.25x
Then, the total revenue is:
0.50 * (x + (x + 0.25x))
We rewrite:
0.50 * (x + 1.25x)
0.50 * (2.25x)
Answer:
The following expressions represent possible revenue from the sales:
F. 0.50 (2.25x
C. 0.50 (x + 1.25x)
A. 0.50 [x + (x + 0.25x)]
