Question

find the area of the sheet required to cover both ends of an open cylinder whose curved area is3080cm square and height is 35 cm​

Answer 1

Step-by-step explanation:

Given:

CSA = 3080 cm²

H = 35 cm

CSA= 2× π ×R× H

3089=2× 3.14 × R × 35

R =14 cm

sheet required = 2× area of circles in both ends

area of circle = πR² = 3.14×14×14 = 615.44

area of sheet = 2 × 615.44 = 1230.88cm²
