Question

from a square of side 14cm,a semi circular portion is cut off find area of the remaining part.
​

Answer 1

Answer:

ANSWER

Side of a square, a=14cm

Radius of each circle, r=27cm

Area of the shaded portion = Area of a square - 4 ×Area of a circle

=a2−4(πr2)

=14×14−4×722×27×27

=196−154

∴ Area of the shaded portion =42cm2.
