Question:
The surface area of a cylinder which exactly fits in a cube of side b is
__________.
Solution:
πb2
Explanation:
When the cylinder exactly fits in the cube of side “b”, the height equals to the edges of the cube and the radius equal to half the edges of a cube.
It means that,
h = b, and r = b/2
Then the CSA of a cylinder be = 2πrh
= 2π (b/2)(b)
= πb2
