Find an expression in terms of radius r for the ratio of surface area to volume
for each of the following objects, given
that their volume is equal to that of the
sphere of radius r:
i A cube.
ii A cylinder with two half-spheres
attached at its bases, and height of
cylinder equal to five times the radius
of its base.
iii Hence, if the sphere has unit volume,
find how many times more surface
area each object will have than the
sphere.

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
