volume of cube = (5.5 cm)^3 = 166.375 cm^3
then our cylinder's height would increase by h , such that
π(49)h = 166.375
h = 1.081 cm
(note that the 9 cm depth of water did not enter the picture)
A glass cylinder with a radius 7 cm has water up to a height of 9 cm. A metal cube of 5 1/2 cm edge is immersed in ti completely. Calculate the height by which the water rises in the cylinder.

calculate the volume and total surface area of a right circular cylinder of height 1m and radius 70cm?
0.49m'3,2.38(3.14)
Give
h=1 m
r=0.7 m
solution
A=2*3.14*r(h+r) =6.28*0.7m(1m+0.7m)
=7.47 m^2
where A- total surface area
V=3.14*r^2h
=3.14*0.7*0.7*1
=1.54 m^3
where V- volume
h=1 m
r=0.7 m
solution
A=2*3.14*r(h+r) =6.28*0.7m(1m+0.7m)
=7.47 m^2
where A- total surface area
V=3.14*r^2h
=3.14*0.7*0.7*1
=1.54 m^3
where V- volume
volume of cube = (5.5 cm)^3 = 166.375 cm^3
then our cylinder's height would increase by h , such that
π(49)h = 166.375
h = 1.081 cm
So,h~1(h is approximately 1)
then our cylinder's height would increase by h , such that
π(49)h = 166.375
h = 1.081 cm
So,h~1(h is approximately 1)
Yes, you are correct! Since the height of the water needed is very small compared to the height of the cylinder (9 cm), we can approximate the solution by taking h to be 1 cm.
