good morning

answer it plz plz ​

Answer 1

Answer:

Area of whole round pizza= πr^2

Area of one slice= πr^2/10

Area of one slice=

$\frac{22}{7} \times 15 \times 15 \div 10$

=>22/7×3×15÷2

=>11/7×3×15

=>33×15÷7

=>

$\frac{495}{7} cm {}^{2} = 70.72cm {}^{2}$

Area of whole square pizza=30×30=900

Now, area of one slice of square pizza=900/12=300/4cm^2=75cm^2

So, the girl who bought square pizza got a better deal by 4 cm^2.

a) Sanjana, approx. by 4 cm^2

Hope, it would help you.
