Question

The ratio of area of sector to the area of circle is a) 360° :x° b) xº: 360° c)xº: 90° d) x° : 180°​

Answer 1

Answer:

b) x°:360°

Step-by-step explanation:

Area of Sector = πr²x/360

Area of Circle = πr²

Ratio ÷

Area of Sector/ Area of Circle

πr²x/360 ÷ πr²

πr²x/360 × 1/πr²

x/360

x°/360°

x°:360°

Answer 2

Answer:

x:360

Step-by-step explanation:

Area of sector =pier^2x/360

Area of circle =pier^2

Ratio

Area of sector /Area of circle

pie r^2/360/pier^2

pier^2/360*1/pier^2

x/360

x°/360°

x:360

Hence Prooved
