Answer:
A. 10cm
B. 8 times
Step-by-step explanation:
The question is on volume of a conical container
Volume of a cone= 
where r is the radius of base and h is the height of the cone
Given diameter= 12 cm, thus radius r=12/2 =6 cm
h=10 cm
B.
If height and diameter were doubled
New height = 2×10 =20 cm
New diameter = 2×12 = 24, r=12 cm
volume = 
To find the number of times we divide new volume with the old volume
Answer:
A) 14
Step-by-step explanation:
Take the width: 6 and multiply it 3 times because it says triple.
That gives you: 6 * 3 = 18
Then subtract 4 because it says four inches less than.
That gives you: 18 - 4 = 14
Let us try to formulate the expressions one by one.
let the number be x.
Step 1:
six time the number is 6*x = 6x
Step 2:
product of the number and -3 is -3x
Step 3:
now let us make equation for it:
adding 3x on the left side,
dividing right side by 9
x=45/9 = 5
So the number is x=5
Answer:
The exact form is 12/5 but the simplified one is 2 2/5
