1. Answer:

   The following details are as below :

   s.l =?

   total surface area = 704sq

   π= 22/7

   Step-by-step explanation:

   • Total surface area = 704
   • r = 7 cm
   • total surface area = πr(l+r)
   • 704 = 22/7×7( l + r)
   • 32 = 22/7×7( l + 7)
   • 32 = l + 7
   • l = 32 – 7
   • = 25 cm

   hope it will help you
