Answer this 20 points and brainliest! only if you understand it, .

C

Step-by-step explanation:

The cakes which overlap are the small and middle & the middle and large. The total area of overlap for these cakes will be the surface of the smallest layer's base plus the surface of the middle layer's base.

We can find the area by where r is radius which is half the diameter.

Smallest cake - D=7.5, so r=3.75

=10.5625 × π = 33.1830724035 or 33.2

Middle Cake - D=10, so r=5.

=25 × π = 78.5398163397=78.5

We add together 33.2+78.5= 111.7 cm squared

C is the closest.

alot

step-by-step explanation:

its a wood chuck that can chuck wood

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
