2(x - 5) + 3x = x + 6
2x - 10 + 3x = x + 6
5x - 10 = x + 6
4x = 16
x = 4
Therefore, x = 4.
2x - 10 + 3x = x + 6
5x - 10 = x + 6
4x = 16
x = 4
Therefore, x = 4.

Given:
Radius (r) = 4 cm
Height (h) = 10 cm
π = 3.14
Surface Area of the cylinder formula: SA = 2πr^2 + 2πrh
Substitute the values:
SA = 2(3.14)(4)^2 + 2(3.14)(4)(10)
SA = 2(3.14)(16) + 2(3.14)(40)
SA = 100.48 cm^2
Therefore, the surface area of the cylinder with a radius of 4 cm and height of 10 cm is approximately 100.5 cm^2.
Radius (r) = 4 cm
Height (h) = 10 cm
π = 3.14
Surface Area of the cylinder formula: SA = 2πr^2 + 2πrh
Substitute the values:
SA = 2(3.14)(4)^2 + 2(3.14)(4)(10)
SA = 2(3.14)(16) + 2(3.14)(40)
SA = 100.48 cm^2
Therefore, the surface area of the cylinder with a radius of 4 cm and height of 10 cm is approximately 100.5 cm^2.
