Step-by-step explanation:
Length (l) = 44cm
Breadth (b) = 20cm
Circumference = 2πr = 44cm
2 × 22/7 × r = 44cm
r = 44 × 7/2×22
r = 7cm
Total surface area of the cylinder = 2πr(r+h)
= 2 × 22/7 × 7 (7+20)
= 2 × 22/7 × 7 (27)
= 1188cm^2
volume of the cylinder = πr^2h
= 22/7 * 7^2 * 20
= 22/7 * 49 * 20
=3,080 cm^3
