Answer:
84.78 inches cubed
Step-by-step explanation:
You need to comprehend the volume formula for cones
Volume Formula for Cones: V=1/3hπr²
Your measurements:
9 inches for height
3 inches for radius
**Radius is half of a circle and diameter is full of the circle/base.***
Equation:V=1/3 x 9in x π x 3²
You should do 3 squared first so that you can input it into your calculator easily.
V=1/3 x 9in x π x 9
Now on a calculator do 1 divided by 3 which is the "1/3" in the formula.
Then multiply 9, 3.14 for pi, and 9 for radius.
Note: You should do 3.14 for pi not the whole pi symbol on the calculator.
Your answer: 84.78 in cubed
