Answer:
The answer is option 2, by simplifying 9 to 3² to make both powers base 3 and subtracting the exponents.
Step-by-step explanation:
You have to make the expressions into the same base :

Next, you have to apply Indices Law :




The volume of the cone that has a radius of 8 in. and a height of 10.5 in. is: 703.7 in.³
<h3>What is the Volume of a Cone?</h3>
Volume = 1/3πr²h
Given the parameters:
- Height (h) = 10.5 in.
- Radius (r) = 8 in.
Volume of the cone = 1/3πr²h = 1/3π(8²)(10.5)
Volume of the cone = 1/3π(64)(10.5)
Volume of the cone = 703.7 in.³
