What is the volume of a cone (in cubic inches) with a radius of 2 inches and a height of 3 inches?

Hello! The formula for the volume of a cone is πr^2h1/3. That means the volume of the cone is 1/3 of the base (squared radius * height * pi). The radius is 2 inches. 2^2 is 4. The height is 3 inches. 4 * 3 is 12. Pi is an irrational number that repeats, but we can use 3.14 as pi. 12 * 3.14 is 37.68. Keep in mind that this is an answer choice, but it is not the answer. We have to divide that by 3 to find the actual area, because the area of the cone is 1/3 of the base. 37.68/3 is 12.56. There. The volume of the cone is 12.56 cubic inches. The answer is A.

A Galapagos tortoise can 1/5 mile in an hour. How many hours would it take the tortoise to walk 1/6?

polet [3.4K]

Answer:

5/6 hours

Step-by-step explanation:

Create a proportion where x is the number of hours it will take to walk 1/6 of a mile:

$\frac{1/5}{1}$ = $\frac{1/6}{x}$

Cross multiply and solve for x:

1/5x = 1/6

x = 5/6

So, it will take the tortoise 5/6 hours to walk 1/6 of a mile
