Answer:
0.905 in
Step-by-step explanation:
Parameters given:
Volume of cone, V = 3.6 in³
Height of cone, h = 4.2 in
Although the diagram is not shown, this problem can be solved.
The volume of a cone is given as:
V = ⅓ * π * r² * h
r is the radius of the base of the cone
We can find r.
3.6 = ⅓ * π * r² * 4.2
3.6 = 4.399 * r²
=> r² = 3.6 / 4.399
r² = 0.8184
=> r = 0.905 in
The radius of the base of the cone is 0.905 in.

Answer:
Joel's coin collection had 120 dimes and 80 quarters.
Step-by-step explanation:
Given that Joel had a coin collection of two hundred coins, which were dimes and quarters, and the total value was worth $32, to determine how many coins of each type he had, the following equations must be performed:
0.25 - 0.10 = 0.15
200 x 0.10 = 20
32 - 20 = 12
12 / 0.15 = 80
200 - 80 = 120
(80 x 0.25) + (120 x 0.1) = X
20 + 12 = X
32 = X
Therefore, Joel's coin collection had 120 dimes and 80 quarters.
What is the question?
Matt sold 8 tickets at $9 each. 8 tickets x $9= $72
He still has 6 tickets left. 6 x $9=$54
Total tickets=14
Total amount of money when he is done selling the rest of the tickets is $126
J=1
explaination:
2 is greater than or equal to 3
4 - j(1)= 3
