Answer:
The answer is B ⇒ 
Step-by-step explanation:
∵ v = π r² h
∴ r² = 
∴ r = 
∵ r = 10 ft and h = 15 ft
∴ 
Answer:

Step-by-step explanation:
Stare at the numbers. Especially the first two. First one is -11. Second is
. Let's guess you keep multiplying.
. Smells correct, let's confirm with the last one:
. I think we found a pattern. Each element is 7 times the previous one. With some practice you can just write the function, else let's divide by -11 away and let's see what we get:
. Basically, the exponent is 1 less than the value we're evaluating the function. That leads tho the following

Answer:
2√21
Step-by-step explanation:
Diagonal =√(L²+W²+H²)
Diagonal =√(8²+4²+2²)=√(64+16+4)=√84=2√21
Answer:
10
Step-by-step explanation:
Plug the numbers into the distance formula:


Then solve:
You get 10
49^2 or 7 I just know from 6th grade
