Question

Jia's mother prepared three pizza of same size for her daughter and her two friends. just then two more friends joined them. they decided to share the three pizza among themselves. a. If radius of each pizza is 7cm find the area of the share of pizza that each friend get. b. what value of the children is depicted here?

Answer 1

Answer:

92.4 $cm^2$

Step-by-step explanation:

It is given that the radius of the pizza is 7 cm.

Therefore, Area of one pizza =

$\pi r^2=\pi (7)^2\\=153.93\:cm^2$.

Therefore, the area of 3 pizzas = 3(153.93)= $461.81\:cm^2$

The total number of people sharing the pizzas = 3 + 2 = 5.

Therefore, each person's share will be:

$\frac{461.81}{5}=92.4\:cm^2$

Answer 2

Answer: On including Jiya's Mom,each person get 77 sq-cm of pizza.

On excluding Jiya's Mom,each person get 92.4 sq-cm of pizza.

Solution:

Jia's mother prepared three pizza of same size for her daughter and her two friends.As size of each pizza are same,and we know that pizzas are circular on shape.

Radius = 7 cm

Area of one pizza
$= \pi \: {r}^{2} \\ \\ = \frac{22}{7} \times {7}^{2} \\ \\ = 22 \times 7 \\ \\ = 154 \: {cm}^{2}$
So total area of all pizza's are = 3×154

= 462 sq-cm

a) Find the area of the share of pizza that each friend get:

As total members are 6 ( jiya's mom,jiya,and four friends)

each have a share of
$= \frac{462}{6} \\ \\ = \frac{231}{3} \\ \\ = 77 \: {cm}^{2}$

So,each person get a piece of 77 sq-cm of pizza.

If we exclude jiya's mom than,each person get
$= \frac{462}{5} \\ \\ = 92.4 \: {cm}^{2}$


B) What value of the children is depicted here?

Children show that we must always welcome guests,offer food to them and share our food with guest too.
