pieces.

Question 20

Anjana bought the slice of round pizza and Sanjana opted for square slice. Who got a better deal? And by

what quantity?

Answer 1

Answer:

Sanjana,approximately 5cm2

Answer 2

Answer:

sanjana

Step-by-step explanation:

Anjana

diameter of pizza 30 cm

so radii Will be 15 cm

area of circle πR x R

so

22/7 x 15 x 15 = 706.2 ( nearly)

if he cuts into 10 pieces

then 706.2/10=70.62cm

Sanjana

side of square=30

Area of square= S x S

area = 30 x 30= 900

if he cuts into 12 piece

900/12=75cm

75cm>70.62cm
