Question

Find the area of the sector of a circle of radius 18cm with central angle 35°.​

Answer 1

area of sector=angle/360×πr^2

35/360×3.14(18cm)^2=99cm^2

Answer 2

Answer:

Step-by-step explanation:

area of sector= 1/2*r^2*Ф........  where r-radius and Ф angle made by arc in radians...

given : r=18 cm and angle=35 (in degrees)

therefore .....wkt.,

radian measure= (π/180)*degree measure..,

i.e Ф =(π/180)*35

i.e Ф=7π/36...,

area of sector=1/2*(18)*7π/36..,

a=7π/4 cm^2
