Question

solve this question please.​

Answer 1

Answer:

Height of cylinder= 10cm

radius of base= 3.5cm

Total surface area of the article =Curved surface area of the cylinder +2 surface area of a hemisphere

=2πrh+2(2πr²)

=2πr(h+2r)

=2× 22/7

×3.5(10+2×3.5)cm ²

=374cm ²

Answer 2

Step-by-step explanation:

Height of the cylinder =10cm

Radius of the base=3.5cm

TSA of the article =CSA of cylinder +2×SA of hemisphere

=2pirh+2×(2pir)²

=2pir(h+2r)

=2×22/7×3.5(10+2×3.5)cm²

=374 cm²

Hope that HELPS you OUT.....
