square pizza at the same cost. If the
radius of round pizza is 7 cm and
side of square pizza is 12 cm, then
which offer will be beneficial to you?​

Answer 1

Answer:

The round pizza is beneficial.

Step-by-step explanation:

We will find the area of both pizza, the pizza with larger area is beneficial to us.

Area of round pizza = πr²

                                 = 22/7 * 7²

                                 = 22/7 * 49

                                 = 154 cm²

Area of square pizza = a²

                                    = 12²

                                    = 144 cm²

Hence, the round pizza is beneficial.
