Answer:
C
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = 
area of base × height
= × πr² × height
Here diameter = 22, thus r = 11 and h = 22
V = × π × 11² × 22
= × π × 121 × 22
= 
≈ 2787.64 → C
Answer: 5/8
Step-by-step explanation:
You could convert 1/4 to 2/8 because the numbers you're subtracting have a common factor of 2. After subtracting 2/8 from 7/8, you're left with 5/8.
Answer:
x = 4y/3
Step-by-step explanation:
y = 3x/4
Multiply both sides by 4.
4y = 3x
Divide both sides by 3.
x = 4y/3
Answer:
C.
Step-by-step explanation:
The answer is C because when you add the absolute values (distance to zero) of the two numbers, you get the number 8. Divide this by 2, and you will get 4. Then, you add four to the lower number, -6, and you get -2.
