Vsphere=(4/3)pi(r)³
remember that d/2=r, so 2r=d
given
V=2400
2400=(4/3)pi(r)³
times both sides by (3/4)
1800=pi(r)³
divide both sides by pi
1800/pi=r³
cube root both sides
<span>8.30566118415=r
times 2
</span><span>16.6113223683=r</span>
the aproximate diameter isi 16.6 cm
Answer:
Well, you didn't give a picture of the available mapping diagrams, so I can't tell you that. However, I CAN tell you that the relation is not a function.
Step-by-step explanation:
A function occurs when each input only has one output. For example if the input is 5, it can only give 1 y-value out. It cannot give 2,3,4...etc values. This relation is not a function because -5 maps to both -4 and 3. That's one input to two outputs, which breaks the rules of a function.
The second one is correct
Answer:
2
Step-by-step explanation:
10/3 times 6 =20
1/4 (20) -3
Use PEMDAS
1/4 (20) is 5
5-3=2
