Answer:
3.15cm
Step-by-step explanation:
1. Determine where the given numbers go in formula for the volume of the cone.
2. Multiply ⅓ and 12cm to get 4
3. Isolate the section with unknown variables by dividing 125 and 4 to get 31.25 (rounded)
4. Now isolate the r² by dividing π by 31.25 to get 9.95
5. Take the square root of r and 9.95 to get rid of the exponent.
6. The radius is the answer of square rooting 9.95
7. If asked to check your answer, fill in the formula for the volume of the cone with the radius and round the answer to see if you get the volume you were originally given.
Hope this helps! :)
Answer:
$4.24 each
Step-by-step explanation: I did the math. Well but you first subtract the amount of the cookies. Then you have to divided to est of it by six then boom you get the answer.

Hey buddy, here is your answer. Hope it helps you.
Step-by-step explanation:
144 students enter a spelling bee contest.
Step 1
For the semi final round we are told that only 1/6 of the group will make it into that round.
This is calculated as
1/6 × 144/students = 24 students.
This means that only 24 students would make it into the semi final rounds.
Step 2
We are also told in the question that only 2/3 of THAT group would make it into the final round.
" THAT" group been referred to in the question means the number students that made it to the semi final round
This is calculated as
2/3 of that group( the group that made it to the semi finals)
= 2/3 × 24 students
= 16 students.
Therefore, the number of students that will enter the final round of the spelling bee is 16 students.
