Question

verify the total surface area of cylinder radius is equal to 2 cm and height is equal to 5 cm .​

Answer 1

Given,

The Radius of a solid cylinder (r)=5cm

Height (h)=10cm

Hence

Total surface area =2πrh+2πr

2

=2πr(h+r)

=2π×5(10+5)

=π×10×15

=150πcm

Answer 2

Answer: 96

Step-by-step explanation:

The formula for Surface area of cylinder is 2πr(h + r)

Given: Radius(r) = 2cm.

           Height(h) = 5cm.

To Find Surface area of cylinder: 2πr(h + r)

                                                 ==>  2×π×2(5+2)

                                                 ==>  2×24/7×2(7)

                                                 ==>  24×4

                                                 ==>  96.

∴ 96 is the surface area of cylinder with radius 2cm and height 5cm.
