Answer:
3 cm
Step-by-step explanation:
First, find the volume of the cone.
V = 
r²h
V =
(3.14)(9)(12)
V = 113.04
This means the sphere is also 113.04
Use the formula V = 
r³
113.04 =
(3.14)r³
113.04 = 4.19r³
26.98 = r³
3 ≈ r
Answer:
70.8 to one decimal place,
or to be exact : 70.7873
Step-by-step explanation:
In right angle triangles, trigonometry functions can be used
here tan out of sin, cos ,tan seems the most appropriate
tan(x) = opposite/adjacent
tan(x) = 6.6/2.3
x = tan^-1 (6.6/2.3)
x = 70.7873
5x+3y=17
3y=-5x+17
y=-5/3y + 17/3
Graph if it asks.
Answer:
the answer is 1/12
Step-by-step explanation:
it is 1/12 because if there are only a pair you would have 2 dice. and since each die has numbers all the way up to 6 all you have to do is add them. and don't count all the numbers. like add 1+2+3+4+5+6. that's just plain wrong just do add the highest number on each die (6+6)
