VOLUME OF CYLINDER=2002 CM^3
HEIGHT OF CYLINDER = ?
RADIUS OF CYLINDER = 7 CM
V.OF CYLINDER =PIE R^2 H
2002=22/7×7×7×H
2002=7 WILL CANCEL OUT THEN
2002=22×7×H
2002=154×H
2002/154=H
H=13 CM
THEN THE TOTAL SURFACE AREA OF CYLINDER = 2PIE R (H+R)
= 2×22/7×7 (13+7)
=THEN 7 WILL CANCEL OUT
=22×2 (13+7)
=44×20
= 880 CM^2 OKAY.. THIS IS YOUR SOLUTION BUDDY..^_^ :-)

Answer:

The height of cylinder=13cm

Total surface area of cylinder=880cm²

Step-by-step explanation:

Radius of cylinder=7cm

volume of cylinder=2002cm³

volume of cylinder = πr²h

                        2002=22/7×7²×h

                        2002=22/7×7×7×h

                        2002=22×7×h

                        2002=154×h

                        2002/154=h

                            h=13cm

total surface area of cylinder=2πr(h+r)

                                                  =2×22/7×7×(13+7)

                                                  =2×22×20

                                                  =880cm²
