Question

curved surface area of right circular cylinder is 308m square if the radius of the base of the cylinder is 3.5 metre find its height​

Answer 1

h= 10.51

r= 3.5

A=305

formals

h=A

2πr﹣r=308

2·π·3.5﹣3.5≈10.50563m

Answer 2

Step-by-step explanation:

curved surface area of right circular cylinder=308 m²

radius of cylinder=3.5 m

so, C.S.A of cylinder=2πrh

308 =2×22/7×3.5×h

308 =44×0.5h

h=308/22.4

h=11/8(1.375) m
