Question

if the CSA and radius of a right circular cylinder are 24200cm and 35 cm .Find it's height​

Answer 1

Answer:

Step-by-step explanation:

Given :

CSA = 24200 cm²

radius(r) = 35 cm

height(h) = ?

we know that ,

curved surface area (CSA) = πr²h

24200 = 22/7 x 35² x h

∴ h = (24200 x 7)/ 35x 35

∴ h = 169400 /1225

∴ h = 138.29 cm
