Answer:
1200
Step-by-step explanation:
it's just 400x3 which is 1200
The answer is C if you think think about it
Volume of a cone:


r²h
Plug the radius and volume in the formula.


10²h = 942
Divide both sides by

.

10²h = 2,826
Divide both sides by pi.
10²h = 900
Divide both sides by 10² (100).
h = 9
The cone's height is 9 units.
Answer:
Step-by-step explanation: I will help you with some of them. For the first one the diameter is 18 because diameter is 2x radius. For number 3. The radius is 2. For number 6. The radius is 13. For number 7. The radius is 17. And for number 9. Diameter is 30
Answer:
Disjoint, because the events cannot occur at the same time.
Step-by-step explanation:
disjoint events are mutually exclusive events.
if a and b are two events then a intersection b will be 0 . they cannot occur at the same time.
here in the given problem let the event A be randomly drawing a jack from a standard deckn of card and evnt B be randomly drawing an ace from a standard deck of card.
since in a same card jack and ace cannot occur they are disjoint events.
therefore randomly drawing a jack from a standard deck of cards and randomly drawing an ace from a standard deck of cards are disjoint events because the events cannot occur at the same time.
