1] 0.23
2] both are same
3] 20/100 *80= 16
Answer:
3
Step-by-step explanation:
the slope id going up at a rate of 3
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
