Find the diameter of a cone that has a volume of 83.74 cubic inches and a height of 5 inches. Use 3.14 for pi.
1 answer:
Start with V=(1/3)x(3.14)x(r-squared)x(h) This is the formula for the volume of a cone
Then plug in the values that you are given in the equation 83.74=(1/3)x(3.14)x(r-squared)x(5 inches)
Now combine "like terms" 83.74=(5.233333)x(r-squared)
Next you want to get "r" by itself, so by using order of operations we divide by 5.233333 on both sides and then you are left with 16=r-squared
Now to get rid of the "squared" you find the square root of both sides and you're left with 4=r
Now that you have the radius and the question is "what is the diameter" simply double the radius and so you are left with 8
The answer is 8 inches

Answer:
y = 2m-5
Kim's age now is y = 2m-5
Step-by-step explanation:
Let m represent martas age now and y represent Kim's age now
Given;
Five years ago Kim's age was twice as great as martas age.
(y-5) = 2(m-5)
Solving for y;
y-5 = 2m-10
y = 2m-10+5
y = 2m-5
Kim's age now is y = 2m-5
The answer is 4/12
That easy
X-4y=1
2x+y=11
ok so you have x-4y=1 and 2x+y=11
3x-3y=12 is your answer
