Question

the radius and length of a solid cylinder is measured as r=(10 0+/-
0 2) cm i=(20 0+/- 0 5) cm calculate volume and surface area of
cylinder and error in them?

Dear Student , We know that , A=2πrh+2πr2A=2×3
14×10×20+2×3
14×(10)2A=628 cm2Now ∆AA=2×∆rr∆A=2×∆rr×A∆A=2×
210×628∆A=25
12cm2now Surface area will be = (628+25
12)cm2Similarly for the volume v= πr2hRegards

the radius and length of a solid cylinder is measured as r=(10.0+/- 0.2) cm. i=(20.0+/- 0.5) cm. calculate volume and surface area of cylinder and error in them?
