Find the area of the base:
(4)(3) = 12sqft
Find the area of the sides:
(4)(12) = 48sqft
There are 2 bases and 4 sides, therefore:
12(2) + 48(4) = 24 + 192 = 216sqft
Hope this helps :)
Answer:
what do you need help with
Step-by-step explanation:
We know that the volume of a sphere is:
V
=
4
3
π
r

where
r
=
10
2
=
5
ft
is the radius;
we need half of this, so we use:
V

=
261.8
ft

giving a total weight of water of:
W
=

Answer:
16 cm
Step-by-step explanation:
Circumference is equal to 2 pi r.
Isolating r gives us C/2pi = r
50.26/2pi = 8, exactly.
Diameter is equal to 2r, so the diameter is 16 cm.
