What is the approximate volume of a cone with a height of 12 in. and radius of 9 in.? Use 3.14 to approximate pi, and express your final answer to the nearest hundredth.

1017.88

Step-by-step explanation:

The volume of a cone is V=1/3hπr²

First, we are going to do exponents: what is 9*9? 81. So now our equation is V= 1/3h * 3.14 * 81 (Pi is 3.14, so we filled that in too.)

Now we need to find 1/3 of our height, or 1/3 * 12, which is 4. Our equation is now V= 4 * 3.14 * 81

Solve and you get 1017.88

I hope this helped, please mark Brainliest, thank you!

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
