Answer the following.
Solution:
Given data
Width of rectangle (B) = 5 cm
Height of cylinder will be length of rectangle.
Height of cylinder(H) = 25 cm
Given data
Width of rectangle (B) = 5 cm
Length of rectangle(L) = 25 cm
If rectangle strip is rotated completely about the 25 cm side, it will form cylinder.
Height of cylinder will be length of rectangle.
Height of cylinder(H) = 25 cm
Radius of cylinder will be width of rectangle.
Radius of cylinder (R) = 5 cm
We know the formula of total surface area of cylinder is given belowT.S.A of cylinder = 2 × π × R × (H + R)
T.S.A of cylinder = 942.857 cm²
