Answer 1

Answer:

Radius of circular table top = 1.6m

Area of circular table top = 3.14×1.6×1.6 =8.0384 meter square

Cost of polishing 1 meter square=15

Cost of polishing circular table top =8.0384×15 =120.576rs.

Step-by-step explanation:

$area \: of \: circle \: = \: \pi {(radius)}^{2}$

Answer 2

Diameter= 1.6m
Radius= 0.8 m
Polished surface area = pi r^2
= 3.14 . 0.8 . 0.8
= 2.0096 m2
Rate of polishing= 15 Rs
= 15. 2.0096
= 30.144
