Question

Find the height of the cylinder whose volume is 1.54m3 and diameter of the base is 140cm.​

Answer 1

Answer:

D=140cmm

so R=140/2=70cm=70/100=0.07m

volume of cylinder=1.54m³

Πr²h=1.54m³

22/7 * 0.07*0.07*h=1.54m³

h=1.54m³*7/22*1/0.07*1/0.07

h=0.49*1/0.07*1/0.07

h=100m

is it right or wrong answer

Answer 2

Step-by-step explanation:

volume of cylinder = 1.54m^3 =154cm

• (1mts=100cm)

diameter of base = 140cm

radius = 140/2 = 70cm

πr^2h = 154

=> 22/7 * 70 * 70 * h = 154

=> h = 154 * 7/ 22 * 70 * 70

=> h = 1/100

=> h = 0.01 cm

height in metre = 1 mts
