Acylindrical vessel open at the top has a base radius 10.5cm and height 14cm .find the cost of painting the inner part of the vessel at the rate of rs 10 per 100sqcm

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

40 x 50 = 2000

step-by-step explanation:

answer: your answer is a

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
