121=3.14*3*square root of r^2+h^2
kati45 [8]

First, isolate . To do so, divide both sides by .Then, eliminate the radical. So, square both sides of the equation To have h^2 only at the right side, subtract both sides by r^2.And, to have h only, take the square root of both sides of equation

What will replace question mark? <br> If 1243=21 , 2415=36, 3241=25, 4521=27 then 3542=?
qwelly [4]

The answer of 3542=48, if the given is 1243=21 , 2415=36, 3241=25, 4521=27.

Step-by-step explanation:

The given is,

              1243=21

              2415=36,

              3241=25,

              4521=27

Step:1

          For, 1243 = 21

          Above is solved by,

                    (1+2)×(4+3)=21

                           (3)×(7)=21

                                 21=21

          For, 2415 = 36

          Above is solved by,

                    (2+4)×(1+5)=21

                           (6)×(6)=36

                                36=36

          For,3241= 25

          Above is solved by,

                    (3+2)×(4+1)=25

                           (5)×(5)=25

                                25=25

          For, 4521= 27

          Above is solved by,

                    (4+5)×(2+1)=27

                           (9)×(3)=27

                                 27=27    

           For, 3542 = ?

          Above is solved by,

                                     = (3+5)×(4+2)

                                     =(8)×(6)

                            3542=48

Result:

       The answer of 3542=48, if the given is 1243=21 , 2415=36, 3241=25, 4521=27.
