Question

the curved surface area of a right circular cylinder is 440cm3 and its radius is 7cm its height​

Answer 1

Answer:

Given : C.S.A = 440cm² you didn't know area is always in square means cm² or m² volume is in cubes form means cm³ or m³.

C.S.A of cylinder = 2πrh= 2×22/7× 7×h

440 = 2×22h

44h = 440

h = 440/44

h = 10cm
