b) Anjana, approximately 4 cm2

c) Sanjana, approximately 5 cm2

d) Anjana, approximately 5 cm​

Answer 1

Answer:

sanjana approximately by 4 cm2

Step-by-step explanation:

area of one slice in round pizza is 70.65 cm2

while in square it is 75 cm2

so, area of one slice in square pizza is approximately 4 cm2 greater than in round pizza

Answer 2

Sanjana got a better deal by 4 cm^2

Step-by-step explanation:

• Anjali took a round pizza
• Radius of circle= 15cm
• Area= π x r^2 = 22 / 7 x (15)^2
• Area = 707.14 cm²
• Area of one piece of pizza= 707.14 / 10 = 70.71cm²
• Sanjana took square pizza:  
• Length of a square side = 30cm
• Area of square = side x side = 30 x 30 = 900cm²
• Area of one piece of pizza that Sanjana bought = 900/12 = 75cm²
• Thus Sanjana got a better deal by approximately = 75 - 70.71  = 4cm²
