<h3>What is cylinder?</h3>A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder.
Given that,
Radius of pipe a is 6 cm, and the radius of pipe b is 2 cm.
We know that the volume of cylinder is :-
where r is radius and h is height of the cylinder.
If two figures are similar then ratio of volume is equal to the cube of any dimension.
The ratio of the volume of Pipe a to the volume of Pipe b :-
=
Hence, The ratio of the volume of pipe a to the volume of pipe b is 27:1 .

10 people who build at the same rate can frame a house in 6 days. That means it will take one person days to finish the house.
Which means that it will take 4 people days to finish the house.
So, the fractional part of the house 4 people can frame in 3 days will be
Thus, Option D is the correct answer.
