Answer 1

$\huge\mathfrak\red{answer}$

Given:

Slant Height, l=45 cm

Top radius =28 cm

Bottom radius =7 cm

Height =45 cm

Curved surface area =πl(r1+r2)

=   22

  ____×45  $​ (7+28)$

     7

=4950²cm

Answer 2

Given:

Slant Height, l=45 cm

Top radius =28 cm

Bottom radius =7 cm

Height =45 cm

Curved surface area =πl(r1+r2)

= 22

____×45 (7+28)(7+28)
