Answer:
15
Step-by-step explanation:
12/8 =1.5 * 10 =15
Option B) Determine the volume of the cake V= πr²h and divide that amount by 18
<u>Step-by-step explanation:</u>
- It is given that, the birthday cake is in the shape of the cylinder.
- Therefore, to find the entire volume of the cake, the volume of the cylinder formula is used.
<u>The volume of the cylinder is given by,</u>
Volume of the birthday cake = πr²h
After that, it was asked to find the volume of each piece of the cake.
In this case, the birthday cake is cut into 18 pieces.
We already know the total volume of the birthday cake which is πr²h.
In order to find the volume of each piece of cut cake, the total volume must be divided by the number of parts it has been cut into pieces.
Here, the whole part of the cake is 1.
The number of parts it has been divided after it is made into pieces = 18 parts.
Therefore, the volume of the birthday cake must be divided by 18 to get the volume of each piece of cake.
Option B) Determine the volume of the cake V= πr²h and divide that amount by 18 is correct.
Answer:
y = 2
Step-by-step explanation:
5y - 3 + y = 9
6y = 12
y = 2
Is there more to this question?
Answer:
B
Step-by-step explanation:
Both of the two numbers should equal the same amount when dividing.
For example, in A
25÷15=1.666...
30÷18=1.666...
Both of these answers are the same so that means that 25/30 is equivalent to 15/18
When you're dividing B though, they don't equal the same amount
90÷15=6
105÷18= 5.833...
that means that 90/105 does NOT equal 15/18
good luck
