Pls help me it’s geometry

4.71

Step-by-step explanation:

Angle = 60°

Radius r = 3

Pi = 3.14

Area of sector = Angle of sector/360° ×pi • r²

= 60/360 × 3.14 × 3²

= 1/6 × 28.26

= 4.71 cm²

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
