Question

rangoli aroopn pattern (area related to circles) make a rangoli of circular shape find the area of rangoli make a segment and find the area of segment make a sector and find the area of sector

Answer 1

Given :  Rangoli of circular shape

To Find : area of Rangoli

area of segment

area of sector

Solution:

Measure radius of Rangoli = R

Area of Rangoli = πR²

Draw a segment AB

Measure  ∠AOB  =  α°

Area of Minor segment  = (α/360)πR² - (1/2)R²Sinα°

Area of Major segment  = Area of circle - Area of Minor segment

or

((360 -α)/360)πR² + (1/2)R²Sinα°

Area of  Sector = (α/360)πR²
