Question

Area of a sector of a circle if radius 14cm and sector angle 80degree is _______​

Answer 1

Step-by-step explanation:

Given :-

sector of a circle if radius 14cm and sector angle 80degrees

To find:-

Area of a sector

Solution:-

Radius of the sector(r)=14 cm

Angle of the sector (x°)=80°

Formula:-

If the radius is 'r' units , angle is 'x°' then the area of the sector (A)=(x°/360°)×πr^2 Sq.units

Area of the sector(A)=

(80°/360°)×(22/7)×14×14 sq.cm

=>(2/9)×(22/7)×196 sq.cm

=>(2×22×196)/(9×7) sq.cm

=>(2×22×7×28)/(9×7) sq.cm

Cancelling 7

=>(2×22×28)/9 sq.cm

=>1232/9 sq.cm

=>136.888.... sq.cm

=>136.89 sq.cm(approximately)

Answer:-

Area of the sector=136.89 sq.cm
