Question

the radius and slant height of a cone are 4cm and 25cm respectively.Find the curved surface area of that cone. (π= 3.14)

Answer 1

Given:-The radius and slant height of a cone are 4 cm and 25 cm respectively
Curved surface area of cone=πrl=3.14×4×25=314cm^2

Answer 2

Radius of cone,R=4cm

Slant Height,L=25cm

Curved Surface area of cone=πrl

=>(3.14×4×25)cm^2

=>(3.14×100)cm^2

=>314cm^2
