Question

plz find the surface area ?.... (Pi=22/7).....​

Answer 1

Answer:

Surface area = πr^2

= 2πr^2

= 2 × 22/7 × 7/2 ×7/2

= 77m^2

hope it will help you ❣️

Answer 2

Answer:

Surface Area of the Cylinder = 385m²

Step-by-step explanation:

We Have :-

Height = 14m

Diameter = 7m

Radius = 3.5m

To Find :-

Surface Area

Formula Used :-

TSA Of Cylinder = 2 pi r h + 2 pi r²

Solution :-

TSA = 2 × 22/7 × 3.5 × 14 + 2 × 22/7 × 3.5 × 3.5

= 308 + 77= 385m²

TSA Of Cylinder = 385m²
