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
For the triangle question, it should probably be A. Sorry if it's wrong.
18/24 = pink roses... 75% of the roses are pink.
