Question

From a circular sheet of radius 14cm a circle of radius 7cm is removed. Find the area of the path.

Answer 1

Answer:

Area of path =

$\pi( {o}^{2} - {i}^{2} )$

o= radius of outer circle

i= radius of inner circle

so

Area of path =

$\pi \times (196 - 47)$

$\pi \times 147$

=462 cm square
