1. Step-by-step explanation:

   diameter =15

   and , radius =15/2=7.5cm

   pattern in circle =22/7 (we know that)

   therefore,

   remaining area = 6400 -22/7×7.5×7.5cm

   6223.21cm.

   please mark best answer and thank me please I

2. Step-by-step explanation:

   The required remaining area is 6223.21cm.

   Step-by-step explanation:

   80× 80⇢ 6400cm

   Diameter⇢ 15cm

   Radius⇢ 7.5cm

   π⇢22/7

   Remaining area ⟹ 6400- 22/ 7

   (7.5)^{2}(7.5)

   2

   Remaining area

   ⟹6400 − 722×(7.5)^2

   6223.21cm

   Hence, the required remaining area will be 6223.21cm
