Answer 1

$\huge \red {\colorbox{gold}{♡Required \: Answer♡}}$

So , 80× 80⇢ 6400cm

Diameter⇢ 15cm

Radius⇢ 7.5cm

π⇢22/7

Remaining area --> 6400- 22/ 7

(7.5)^{2} Remaining area⟹6400 − 722×(7.5)^2

6223.21cm

Hence , the required remaining area will 6223.21cm

Answer 2

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
