Find the area off the sector of circle with radius 4 cm and the angle 30° the find the area of corresponding major sector?ans. We have,Let the radius of circle r=4cm.Angle θ=30 oArea of sector of circle= 360 oθ ×πr 2= 360 o30 o ×π×4×4= 12π ×16= 34π = 34 ×3.14=4.186cm 2Area of major sector = Area of circle-area of minor sector=πr 2 −4.186=3.14×4×4−4.186=3.14×16−4.186=50.24cm. 2 |
