Evaluate C(5, 0). Combinations

1 answer:

5 0

The general equation for the combination is as shown below,

C(n,r) = n!/(r!(n-r)!)

Note that the symbol "!" means factorial.

In our example, n = 5 and r = 0. Substituting the known values,
C(5,0) = 5!/(0!(5-0)!) = 1

The answer to this item is 1.

The capacity of cylinder tank is 539 litres . if its height is 1.4m then find the area of base

Dennis_Churaev [7]

Step-by-step explanation:

Solution:

Here,

Volume of the tank=539 litres

=539×1000cm^3=539000cm^3

Height=1.4×100cm=140cm

Let the radius of the base be r cm

Then,

22/7×r^2×140=539000

or,r^2=539000×7/22×140

or,r^2=1225

or,r=35 cm

So,

Area of base=pie r^2

=22/7×35^2

=3850 cm^2

Keep smiling and hope u r satisfied with my answer.Have a good day :)
