Answer 1

Answer:

231/4

can you give me your number please

Answer 2

Answer:

The area of each piece is 57.75 cm²

Step-by-step explanation:

Given,a pizza of diameter 21 cm.

We know shape of pizza is circular.

Now, radius = diameter ÷ 2

So, radius = (21÷2) = 10.5 cm

We know,area of a circle $= \pi {r}^{2}$

Where r is the radius of the circle.

Here r = 10.5 cm

So,area of the pizza

$= \pi \times {10.5}^{2} \\ = \frac{22}{7} \times 10.5 \times 10.5 \\ = \frac{22 \times 105 \times 105}{7 \times 10 \times 10} \\ = \frac{22 \times 15 \times 105}{10 \times 10} \\ = \frac{34650}{100} \\ = 346.5 \: {cm}^{2}$

It is also given that the pizza is divided into 6 equal parts.

So,area of each part

$= \frac{346.5}{6} \\ = 57.75 \: {cm}^{2}$
