Answer:
1/216
Step-by-step explanation:
The ratio of volumes of similar shapes is the cube of the scale factor. The filled portion of the cone is similar to the entire cone.
<h3>Linear scale factor</h3>
If the filled height is 1/6 of the total height, the scale factor for linear dimensions is 1/6.
<h3>Volume scale factor</h3>
The scale factor for the volume is the cube of the scale factor for linear dimensions. it is ...
(1/6)³ = 1/216
The volume of the filled portion of the cup is 1/216 of the volume of the cup.
Using Heron's formula where s = 9 ...... and a = b = c = the side lengths .....we have......
A = √[s(s -a)^3] = √[4*3^3] = √[4*27] = √[4*9*3] = √[36*3) = 9√3 sq. in.
Answer:
16

Hey there,
To do this you need to work bout what 10% of 340 minutes is.
To do this do 340 / 10 = 34
34 is 10% of 340.
Now you should subtract the 10% from the original time.
340 - 34 = 306.
The answer is 306 minutes.
That was the long method. The short method is to use percentage multipliers.
To do this you do 340 x 0.9 = 306.
Either way you would get the same answer of 306 minutes.
Hope This Helps You!
Good Luck Studying :)
