Question

A right triangle, whose base and height are 15 cm. and 20 cm. respectively is
made to revolve about its hypotenuse. Find the volume and surface area of the double cone so
formed​

Answer 1

Answer:

Let Z be the number

Z = 13x + 11 where x is the quotient when Z is divided by 13

Z = 17y + 9 where y is the quotient when Z is divided by 17

13x + 11 = 17y + 9

13x + 2 = 17y since x and y are quotients they should be whole numbers . Since y has to be a whole number the left hand side should be multiple of 17

The least possible value of x satisfying the condition is 9 and y will be 7

The answer is 13*9 + 11 = 128 or it is 17*7 + 9 = 128

This is the least number possible. There will be multiple answers and will increase in multiples 17*13 = 221 like 349 , 570, etc

Answer 2

Step-by-step explanation:

Let z be the number.

z= 13x+11 where x is the quotient when z is divided by 13..

z= 17y+9 where y is the quotient when z is divided by 17..

13x+11=17y+9

13 x+2=17y since x and y are questions they should be whole numbers. since why has to be a whole number the left hand side should by multiply of 17.

the least possible value of x satisfying the condition is 9 and y will be 7.

The answer is 13*9+11=128 or it is 17*7+9=128

This is the least number possible. There will be multiple answers and will increase in multiples 17*3=221 like 349,570 etc..
