Question

the curved surface area of a cylinder is 1520cm² and its volume is 10,640cm³ . find its height​

Answer 1

Answer:

17.27

Step-by-step explanation:

c s a of cylinder=2πrh=1520cm2

h=1520/2πr

volume=πr2h=10640cm2

πr2×1520/2πr=10640

760r=10640

r=10640/760

r=14cm

h=1520/2×22/7×14

h =1520/88

h =17.27cm
