<PRE><B>Question 1026545</B>
area, not including the top and bottom circles, is 

A = pi(R_1+R_2)s 
 
 
 = pi(R_1+R_2)sqrt((R_1-R_2)^2+h^2). 

= 3.142*(70)*sqrt(6^2+45^2)

=9984.88

Area of Base =pi*r2^2

= 3.142 * 38^2

=4537

Total area = 9984.88+4537

=14521.88 in^2

both sides 

14521.88 in^2 *2

29043.76 in^2

1 litre  = 500 in^2

Number of litre = 58 litres

Add 5% waste 

=61 litres
