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
if you mean that 3x+3=0 then x should equal 0
Answer:
C
Step-by-step explanation:
If the number's a fraction, which this one is, the denominator will always be that little number by the radical, and the whole number will be in the root. Hope this helps!
3y = -2x + 2
y = x + 4 (Substitute the y)
3(x + 4) = -2x + 2 (Distribute)
3x + 12 = -2x + 2 (Add 3 to both sides)
+3x +3x
------------------------------------------
12 = 1x + 2 (Subtract 2 from both sides)
-2 - 2
------------------------
10 = 1x (Divide by 1 on both sides)
10/1 = 1x/1
x = 10
This is your x-coordinate
