V = π r^2 h/3.
( volume = pi x radius squared x height / 3)
To find the volume for this question, you would set up the equation like this:
V = π x 2^2 x 12 / 3
Then, following the order of operation, you would do the following:
V = π x 4 x 12 / 3
(You get the 4 from 2 squared)
V = π x 4 x 4
(You get the second 4 from dividing 12 by 3)
V = π x 16
(You get 16 from multiplying 4 and 4)
V = 16π
(You get 16π from multiplying 16 and π, and the number is always in front of the π, so you would never get a π16, it would only be 16π)
So, your volume would be 16π, which is answer D.

Since there is sign +, we expect it to be the sum. Among all choices, only the last one includes summation, and that is sum of cubes.
Let's check it out.
Sum of cubes can be expresses as:
a³ + b³ = (a + b)(a² - ab + b²)
Let's see what are cube roots of 125 and 8:
∛125 = ∛5·5·5 = ∛5³ = 5 ⇒ a = 5
∛8 = ∛2·2·2 = ∛2³ = 2 ⇒ b = 2
Now, let's implement that in the equation of sum of cubes:
5³ + 2³ = (5 + 2)(5² - 5·2 + 2²)
125 + 8 = 7 · (25 - 10 + 4)
133 = 7 · 19
133 = 133
Therefore, sum of cubes is the right answer.

Answer:
fish tank is 14.87 ≈ 15 inches tall.
Step-by-step explanation:
Given : A rectangular fish tank contains 3,240 cubic inches of water. The dimensions of the base of the fish tank are 12 inches x 18 inches.
To find : How tall is the fish tank.
Solution : We have given that volume of fish tank = 3240 cubic inches.
Length of tank = 12 inches.
Width of tank = 18 inches .
Volume of rectangular tank = length * width * height
3240 = 12 * 18* height .
3240 = 216 * height.
On dividing both side by 216 and switching the sides .
Height = .
Height = 14.87 inches
Therefore, fish tank is 14.87 ≈ 15 inches tall.
3240 = 18 x 12 x H
3240 = 216 x H
H = 3240 / 216 = 15 inches

Answer:
1/5 · 1/5 · 1/5 · 1/5
Step-by-step explanation:
One way of interpreting exponents is as repeated multiplication. When you see (1/5)⁴, you can read that as "4 copies of 1/5, multiplied together." That expansion looks like (1/5)⁴ = 1/5 · 1/5 · 1/5 · 1/5
