You can calculate the area of the whole pizza according to the formula: S=1/2*π*r². And the area of 8 piece is 1/8S while the area of 12 piece is 1/12S. The answer should be 1/8S-1/12S=4/3π.
Answer:
5(y / 7)
Step-by-step explanation:
A quotient is the answer to a division problem. This tells us that y and 7 are being divided.
We have (y / 7) so far.
Five times this quotient (y / 7) can be represented by 5*, as the quotient is being multiplied by 5.
The final expression can be shown as: 5(y / 7).
