Answer:
D. 151 cu. in.
Step-by-step explanation:
Given: Cone; Radius = 4 in, Height = 9 in.
To find: The volume of the specified cone
Formula: 
Solution: A cone is a solid that has a circular base and a single vertex. To calculate its volume multiply the base area (area of a circle: π × r²) by height and by
: volume = (
) × π × r² × h.
I think the slope is m=-3 I hope it’s correct
Answer:
Step-by-step explanation:
She simplified it wrong because you're only supposed to simplify it with the same numbers. For example: simplify 2/4. You divide it by 2/2. You do the same and it will be correct.
Answer:

Step-by-step explanation:



Apply the law of exponents, when dividing exponents with same base, we subtract the exponents.
