Jia's mother prepared three pizzas of same size for her daughter and her two friends. just then two more friends join them. they decided to share the three pizzas among themselves. if radius of each pizza is 7cm, find the area of share of pizza that each friend gets.

Answer 1

area of one pizza=πr^2
=22/7×(7)^2
=154
area of 3 pizzas=154×3
=462
area of pizza shared by each student=462/5
=92.4

Answer 2

Area of 3 pizzas = 3 × {/pie} r^{2} = 3 × 22 × 7 = 462 cm^2

There are totally 3 + 2 = 5 friends

Dividing cake among these 5...

= 462/5

= 92.4 cm^{2}

Each one gets 92.4 cm^{2} of share of piece of cake
