Question

for cylinder. radius =7cm height =13 CM total surface are of cylinder =......sqcm​

Answer 1

Step-by-step explanation:

so the formula of total surface area of cylinder is

2πrh+2πrsquare

as r= 7cm and h= 13cm

so the total surface area= 2πrh+2πrsquare

2×22/7× 7 × 13+ 2× 22/7× 7×7

44/7×7×13+ 44/7×49

44×13+44×7

572+308

= 880

therefore the total surface area of cylinder= 880sqcm

Answer 2

Answer:

Answer 880 cm square

Step-by-step explanation:

Total surface of cylinder=2πr(r + h)

Total surface of cylinder = 2× 22/7 (7 + 13)

44×20= 880 cm square इसमें 7 से 7 cutहो जाएगा और जो ब्रैकेट में 7+13 = 20हो जाएगा और वह ब्रैकेट की वजह से और 44 keep sath multiply how jayega
