Radius of a sphere is 70mm.find the cost of painting the curved surface @ rs 0.02 percm

Answer»

Step-by-step explanation:

CSA OF SPHERE = 4/3πR^3

= 4/3×22/7×7×7×7

=4/3×22×14

=4312/3 cm^2

RATE OF COST

1CM ^2=Rs.0.02

4312/3 cm^2=0.02×4312/3

=0.02× 1437.33

=28.74666

cost of painting =Rs.28.75(approx)
