Question

A circle of radius 4cm is cut out from a square piece of an aluminium sheet of side 8cm. what is the area of the left

aluminium sheet. (Take π = 3.14)​

Answer 1

Area Left = 13.76 cm²

Step-by-step explanation:

GIVEN

Radius Of Circle = 4 cm

Side Of Square = 8 cm

___________________________

TO FIND

Area left

___________________________

We know that,

Area Of Square = Side × Side = Side²

Area Of Square = 8 × 8

Area Of Square = 64

Area Of Square = 64 cm²

___________________________

We know that,

Area Of Circle = π × r²

Area Of Circle = 3.14 × 4²

Area Of Circle = 3.14 × 16

Area Of Circle = 50.24

Area Of Circle = 50.24 cm²

___________________________

We know that,

Area Left = Area Of Square - Area Of Circle

Area Left = 64 - 50.24

Area Left = 13.76

Area Left = 13.76 cm²
