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.

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )
