Is this on flvs because I'm on it also
We know that the volume of a sphere is:
V
=
4
3
π
r
3
where
r
=
10
2
=
5
ft
is the radius;
we need half of this, so we use:
V
2
=
2
3
π
r
3
=
261.8
ft
3
giving a total weight of water of:
W
=
261.8
⋅
62.4
=
16
,
336
pounds
lol sorry I’m late it’s 21 though
It is choice 2 the correct answer
Answer:
(a) 
In this question, you can simply just multiply the exponent of 2 and the exponent of 5, in order to get a power of 10.
(b) 
For this question, we need to organize the numbers as a fraction
We need to subtract the exponents from each variable. In 
and y, we need to subtract 3-1 to get 
. In 
and 
, we need to subtract 7-3 to get 
. Now, we can divide 12 and 6 normally to get 2. So, the answer would be .
