The diameter of cylinder is 2.28 cm and area of wrapper is 60.56π cm².
A cylinder is a three-dimensional solid figure which has two identical circular bases joined by a curved surface at a particular distance from the center which is the height of the cylinder.
Here, Given area of cylinder = 25π cm²
Height of cylinder = 11 cm.
Now, Area of Cylinder = 2πrh
25π = 2πr X 11
25 = 22r
r = 25 / 22
r = 1.14 cm
Then, diameter = 2r = 2 X 1.14 = 2.28 cm
Now area of wrapper = total surface area = 2πr(r + h)
= 2π X 2.28 (2.28 + 11)
= 4.56π X 13.28
= 60.56π cm²
Thus, the diameter of cylinder is 2.28 cm and area of wrapper is 60.56π cm².
