Question

the diameter of the base of a cylindrical is 7cm and volume of 577.5 find the height​

Answer 1

Answer:

15 cm

Step-by-step explanation:

diameter = 7cm

radius = 7/2cm

volume of cylinder = 22/7*r*r*h

=22/7*7/2*7/2*h=577.5

=22*7/2*1/2*h=577.5     (7divided by 7/2=1/2)

11*7/2*h=577.5                (22 divided by 1/2=11)

h=577.5*2/7*1/11

h=577.5*2/77

h= 577.5*2/77

h=1155/77

h=15 cm
