The required arrangement of volumes in increasing order will be

a) d) c) b)

Explanation:

Since we have given that

cone with different diameters and heights all we need to do is to find the volume of cones :

As we know the formula for volume of cone which is given by

$Volume=\frac{1}{3}\pi r^2h$

a) Diameter = 20 units

Radius = 10 units

Height = 12 units

So, Volume is given by

$v=\frac{1}{3}\times \frac{22}{7}\times 10\times 10\times 12=1257.14\ cubic\ units$

b) Diameter = 18 units

Radius = 9 units

Height = 10 units

So, Volume is given by

$v=\frac{1}{3}\times \frac{22}{7}\times 9\times 9\times 10=848.57\ cubic\ units$

c) Radius = 10 units

Height = 9 units

So, Volume is given by

$v=\frac{1}{3}\times \frac{22}{7}\times 10\times 10\times 9=942.85\ cubic\ units$

d) Radius = 11 units

Height = 9 units

So, Volume is given by

$v=\frac{1}{3}\times \frac{22}{7}\times 11\times 11\times 9=1140.85\ cubic\ units$

So, the required arrangement of volumes in increasing order will be

a) d) c) b)
