1. Answer:

   Area = 2468 sq. cm

   Step-by-step explanation:

   [tex]area \: = \: \pi {r}^{2} [/tex]

   r = 28 cm

   by substituting in formula

   Area = π × (28)^2

   if π is taken as 22/7 then,

   Area = (22 / 7) × 28 ×28

   = 22×4×28 sq. cm

   2468 sq. cm

   or if π is taken as 3.14 then,

   Area = 3.14 × 28 ×28

   = 2461.78 sq. cm
