Dear Student
The area of the remaining sheet after the smaller circle is removed will be = Area of the entire circle with radius 4 cm – Area of the circle with radius 3 cm
We know,
Area of circle = πr²
So,
Area of the entire circle = π(4)² = 16π cm^2
And,
Area of the circle with radius 3 cm which is cut out = π(3)² = 9π cm^2
Thus, the remaining area = 16π – 9π = 7π cm^2
Thanks
