The ratio of the area of sector abc to the area of sector dbe is 4:3
Area of a sector
The formula for calculating the area of a sector is expressed as:
A = r²Ф
where:
- r is the radius
- Ф is the subtended angle
For the sector ABC
A1 = (2r)²β
A1 = 4r²β
For the sector DBE
A2 = (r)²3β
A2 = 3r²β
Take the ratios
Ratio= A1/A2
Ratio = 4r²β/3r²β
Ratio = 4/3
Hence the ratio of the area of sector abc to the area of sector dbe is 4:3
