ans. please ​

Answer 1

Answer:

Hi there, I am upendra Verma

I will solve your doubt

Step-by-step explanation:

Given =

1. radius of circular sheet, r3 = 8 cm
2. radius of circle, r2 = 3 cm
3. side of square, a = 4 cm

Area of remaining sheet,

area of circular sheet - area of circle - area of square। (i)

• area of circular sheet = π r1^2
• π *64
• area of circle = π r2^2
• π * 9
• area of square = a^2
• 16

Now,

From (i)

π*64-π*9-16

39 cm
