Question

The radius of a circle is 28 cm and the area of the sector is filled with rain water is 205.4 cm^2. Find the central angle.​

Answer 1

Answer:

Step-by-step explanation:

given:

radius=28cm

area of the sector = 205.4 cm

To find:

theta or cetre angle

solution:

area of sector :

205.4= theta/360×22/7×28×28

205.4= theta/ 360×22×4×28

theta=(205.4×360)/22×4×28= 30( approx)

therefor ,theta =30 degree
