1. Step-by-step explanation:

diameter =15

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

therefore,

remaining area = 6400 -22/7×7.5×7.5cm

6223.21cm.

2. Step-by-step explanation:

The required remaining area is 6223.21cm.

Step-by-step explanation:

80× 80⇢ 6400cm

Diameter⇢ 15cm

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
