Pls give brainliest i really need it
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:
Step-by-step explanation:
r=3 cos 5∅
change ∅ to -∅
r=3cos(-5∅)=3 cos (5∅)
so it does not change.
Hence it is symmetric to x-axis.
change r to -r
-r=3 cos 5∅
or r=-3 cos 5∅
so eq. changes .
Hence it not symmetric to y-axis.
