A circular plate has a diameter of 9 inches. What is the area of the plate?

63.585 inches^2

Step-by-step explanation:

The formula for the area of a circle is...

We need the radius for this, but we have the diameter. Since radius is half of the diameter, we know the radius will be 4.5. We can plug that in.

63.585 inches^2

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
