Answer 1

So , 80x 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

HOPE IT HELPS

6223.21cm

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
