Question

the volume of a cylinder is 770 centimetre cube and circumference of the circular base of the cylinder is 44 cm find its height​

Answer 1

Answer:

Circumference =2pie r

Let the radius be r

ATQ

2 pie r =44

2×22/7×r=44

r=44×7/22×1/2

r=7cm

Therefore, radius =7cm

Volume = pie r²h

Let height be h

ATQ

22/7×7²×h=770

22/7×49×h=770

154h=770

h=770/154=5

Therefore height of the cylinder is 5cm

Step-by-step explanation:

Hope it helps

Answer 2

Answer:

h=5 cm

Step-by-step explanation:

Let the radius of base is r and height is h

Then Volume V= πr²h

circumference of the circular base

=2πr =2*22/7 (r)=44

44r/7 =44

r=44*7/44=7 cm

Then Volume V= πr²h=770 m³

(22/7)*7*7*h=770

22*7*h=770

h=770/(22*7)=110/22=5 cm
