Question

Find the total surface area and
lateral surface area for the solids
with the following dimensions cylinder r=7cm h = 11cm​

Answer 1

Answer:

total surface area= 484 cm sq

Step-by-step explanation:

total surface area of cylinder= 2πrh

= 2 x 22/7 x 7 x 11

= 484 cm sq

Answer 2

Answer:

lateral surface area of cylinder= 484 cm²

Total surface area of cylinder = 792 cm²

Step-by-step explanation:

I Lateral surface area of cylinder = 2 pi rh

r=7 cm, h=11cm, pi=22/7 or 3.14

2 pi rh = 2×22/7×7*11cm

= 2×22×11cm (when we divide them)

= 484 cm²

Answer= 484 cm²

ii Total surface area of cylinder= 2 pi r(r+h)

r=7 cm, h=11cm, pi=22/7 or 3.14

2 pi r(r+h) = 2×22/7×7cm(7cm+11cm)

= 2×22/7×7cm×18 cm

= 2×22×18cm

= 792 cm²

Answer= 792 cm²

So, Latreal surface area of cylinder is 484cm²

Total surface area of cylinder is 792 cm².
