- 1st Circumference = 17.6cm
- C = pi*d
- 17.6 = 3.14*d
- d = 17.6/3.14
- Hence, d = 5.6
- Area = pi*r^2
- Area = 3.14*2.8^2
- Area = 3.14*7.84
- Area = 25 cm. sq.
- 2nd Circumference = 70.4cm
- C = pi*d
- 70.4 = 3.14*d
- d = 70.4/3.14
- Hence, d = 22
- Area = pi*r^2
- Area = 3.14*11^2
- Area = 3.14*121
- Area = 380 cm. sq.
- Total Area = 25+380
- = 405 cm. sq.
- Rate per cm. sq. = ₹10
- Total Cost = 405*10
- = ₹4050.
