Question

a closed circular cylinder has diameter 20 cm and height 30 cm find the total surface area of the cylinder is π= 3.14 ​

Answer 1

Answer:

TSA=Base area+CSA

=2*3.14*10+2*3.14*10*30=6104.6 CM2

Answer 2

Answer:

2512 cm^2

Step-by-step explanation:

Diameter=20cm

Radius=10cm

Height=30cm

Total surface area of the Cylinder=2.pie.r(r+h)

=2×3.14×10(10+30)

=62.8×40

=2512 cm^2
