Sue bought an ice cream cone from Dairy Queen. The cone had a radius of 3cm and a height of 8cm. If I use the formula of (TT=3.14, r=radius, h=height)
2
V=1/3TTr h
Is the answer 50.24 cm3?
Any help is appreciated. If I'm not right could you tell/show me how to figure this out? Thank You
Since v = 1/3 pi r^2 h
I get
v = (1/3)(3.14)(9)(8) = 75.36
How did you get your answer?
Yes, you are correct! The answer is indeed 50.24 cm³.
To calculate the volume of the ice cream cone, you can use the formula for the volume of a cone:
V = 1/3 * π * r² * h
In this case, the radius (r) is given as 3 cm and the height (h) is given as 8 cm. Now, you can substitute these values into the formula:
V = 1/3 * 3.14 * (3 cm)² * 8 cm
First, calculate the value of (3 cm)², which is 9 cm²:
V = 1/3 * 3.14 * 9 cm² * 8 cm
Next, multiply 3.14 by 9 cm² to get 28.26 cm³:
V = 1/3 * 28.26 cm³ * 8 cm
Then, calculate the value of 1/3 * 28.26 cm³, which is 9.42 cm³:
V = 9.42 cm³ * 8 cm
Finally, multiply 9.42 cm³ by 8 cm to get the volume of the ice cream cone:
V = 75.36 cm³
So, the correct answer is 75.36 cm³, not 50.24 cm³. I apologize for the mistake.
