Answer:

Difference in volume between the 10 inch diameter and the 12 inch diameter vinyl records = 3.872 in³

Step-by-step explanation:

Both of the vinyl records will each be modelled as a cylinder

Volume of a cylinder = πr²h

For the 12 inches diameter records.

r = (12/2) = 6 inches

h = thickness = 0.112 inches

Volume = π × (6²) × 0.112 = 12.672 in³

For the 10 inches diameter records

r = (10/2) = 5 inches

h = thickness = 0.112 inches

Volume = π × (5²) × 0.112 = 8.8 in³

Difference in volume between the two vinyl records = 12.672 - 8.8 = 3.872 in³

Hope this Helps!!!

lord [1]

Answer: 1\dfrac13 cups of pineapple juice .

Step-by-step explanation:

Equation of direct proportion between x and y:

\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}

As per given,

Let x = quantity of pineapple juice and y = quantity of orange juice.

x_1=\dfrac13\  , y_1=\dfrac34 ,  y_2=3

Put these values in an equation we get

\dfrac{\dfrac13}{\dfrac34}=\dfrac{x_2}{3}\\\\\Rightarrow\ \dfrac{4}{9}=\dfrac{x_2}{3}\\\\\Rightarrow\ x_2=3\times\dfrac{4}{9}=\dfrac{4}{3}\\\\\Rightarrow\ x_2=1\dfrac13

Hence, he needs 1\dfrac13 cups of pineapple juice .

i have a field 60m long and 110 wide going to be paved i ordered 660000000cm cubed of cement  how thick must the cement be to co
Sveta_85 [38]
<span>First find the area of the field
A=WL
A=(110m)(60m)
A=6,600m^2
Now turn the cm into m
becouse 100cm^3=1m^3
660,000,000cm^3=6,600,000m^3
Now find out how many times you can cover the filled
6,600,000m^3/6,600m^2=100m
So it will be 100m thick.
P.S. I'm assuming you meant you jest forgot the m for 110m.</span>
