The sum of three numbers is 41
Hatshy [7]

Answer:

11

Step-by-step explanation:

let the first number be n , then the second number is 5n and

the third number is 5n - 14

Sum the numbers and equate to 41

n + 5n + 5n - 14 = 41

11n - 14 = 41 ( add 14 to both sides )

11n = 55 ( divide both sides by 11 )

n = 5

Thus

first number = 5

second number = 5n = 5 × 5 = 25

third number = 5n - 14 = 5(5) - 14 = 25 - 14 = 11

The volume of a cylinder is 252π cm3 and its height is 7. What is the cylinders radius?
stiks02 [169]
The volume of a cylinder is given by the formula;
Volume = πr²h, where r is the radius, and h is the height or the length 
Therefore,
252 π cm³ = π r² (7)
           r² = 252/7
              = 36
            r = √36
               = 6 cm .
Hence, the radius of the cylinder is 6 cm
