If a circle with a diameter of 8 cm is reduced by 2 cm, its perimeter and area will be reduced by () cm and () cm respectively

The original perimeter is 8 π cm
After 2 cm reduction, the perimeter is 6 π, 2 π cm or 6.28 cm
The original area is π x 4 & # 178; = 16 π CM & # 178;
Now it is 9 π CM & # 178;
7 π cm and 178;
