What is the surface area of the cylinder whose radius is 6 in and the height is 17 in.

Given the cylinder such that the radius of the base is (r)
= 6 in


Also, given that the height of the cylinder is (h) =
17 in.


We need to find the surface area of the
cylinder.


We know that the surface area of the cylinder is
given by the following equation.


SA = 2*area of the base +
area of the side.


==> SA = 2*A1 +
A2


Let us calculate the area of the
base.


We know that the area of the circle =
r^2*pi


==> A1 = 36*pi = 113.1
in^2


Now we need to find the area of the
sides.


A2 = circumference of the base *
h


       = 2*pi*r * h


        
= 2*6*pi*17 = 204*pi = 640.9 in^2


Now we will substitute
into the surface area.


SA = 2*A1 +
A2


     = 2*113.1 +
640.9


      = 226.2 + 640.9 = 867.1 in^2
(approx.)


Then, the surface area of the
cylinder is 867.1 in^2

Calculate tan(x-y), if sin x=1/2 and sin y=1/3. 0

We'll write the formula of the tangent of difference of 2 angles. tan (x-y) = (tan x - tan y)/(1 + tan x*tan y) ...
