Question

Find the total surface area of the cylindri-
cal object if its radius is 5 cm and height is
10 cm.​

Answer 1

Answer:

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:

471.42 cm^2

Explanation:

radius = 5cm

height = 10cm

TSA = 2× 22/7 ×5 (5+10)

= 2×22/7 × 5 × 15

= 44/7 × 75

=471.42 cm^2
