Question

from a circular sheet of radius 4 cm a circle of radius 3cm is cutoff find the area of the remaining sheet​

Answer 1

Answer:

Find the area of the remaining sheet. (Take π = 3.14) Thus, the area of the remaining sheet is 21.98 cm2.

Answer 2

Answer:

The area of the circular sheet with 4cm radius is,

A=πr²

=16π

The area of the circular sheet with 3cm radius is,

A=πr²

=9π

Since the circle with radius 3cm is removed, then the remaining area is,

A=16π−9π

=7π

=7×3.14

=21.98cm²
