Answer 1

Answer:

Give me full question not half whose surface area cube cuboid cylinder cone sphere hemisphere hollow cylinder etc.

Answer 2

The total surface area of the cylinder is 149.5 cm², whose radius is 2.5 cm and height is 7 cm.

Step-by-step explanation:

Total surface area is the area which contains area of the circular top and base and their curved surface area.

The formula for Total surface area is,

TSA = $2\pi r (h + r)$ square units

where, r is the radius of the cylinder

h is the height of the cylinder

π = 3.14 (constant value)

Given Data

Radius of the cylinder (r) = 2.5 cm

Height of the cylinder (h) = 7 cm

To find the Total surface area of the cylinder

Total surface area of the cylinder = $2\pi r (h + r)$  square units

Substitute the respective values in above formula

Total surface area of the cylinder = 2 × 3.14 ×2.5 ( 7 + 2.5 )

Total surface area of the cylinder = 15.7  ( 9.5 )

Total surface area of the cylinder =  149.15 cm²

Therefore the Total surface area of the cylinder with radius 2.5 cm and height 7 cm is 149.5 cm².
