Answer 1

Answer:

Area of the remaining sheet is 51.44 cm^2cm2

Step-by-step explanation:

The area of a circle with a radius rr is,

Area = \pi r^2Area=πr2

So the area of the circle of radius 2cm is,

Area =\pi \times 2^2=4\pi=12.56Area=π×22=4π=12.56 cm^2cm2

Area of a square with side measurement aa is,

Area= a^2Area=a2

When the side of the square is 8cm, the area is,

Area= 8^2 =64\ cm^2Area=82=64 cm2

The area of the remaining sheet is given by,

Area \ of\ square - Area \ of\ circle = 64-12.56=51.44Area of square−Area of circle=64−12.56=51.44 cm^2cm2
