Angelina has five cakes. She wants to cut them into 2/5 pieces. How many pieces will she be able to cut?
Licemer1 [7]
<span><u><em>Answer:</em></u>
She will be able to cut them into <u><em>12.5 pieces</em></u>

<u><em>Explanation:</em></u>
We know that the total number of cakes is 5 cakes and that the portion of each piece would be </span>\frac{2}{5}<span>.

To know the total number of pieces she can divide, we would simply divide the total number of cakes by the portion of each cake as follows:
number of pieces = </span>\frac{5}{ \frac{2}{5}}
<span>
number of pieces = </span>\frac{25}{2}
<span>
number of pieces = 12.5 pieces

Hope this helps :)

What’s the volume?<br> someone please help
bazaltina [42]

Answer:

17734.55 inches cubed. If you found this helpful, love the answer! Thank you :D

Step-by-step explanation:

Very simple. We find the area of the circle, A=Pi Radius Square.

So 3.14 (15x15)

A≈706.86

The bottom shape is 706.86x24=16964.64

The top is a cone, meaning its V≈3769.91

So 3769.91+16964.64=17734.55
