The volume of a right circular cylinder is 1100 cm3 and the radius of its base is 5 cm. Calculate its curved surface area.
Scorpion4ik [409]

Answer:

  • (C) 440 cm²

Step-by-step explanation:

<u>Volume:</u>

  • V = πr²h

<u>Given r = 5 cm and V = 110 cm³, find h:</u>

  • 1100 = π(5²)h
  • 1100/25 = πh
  • 44 = πh

<u>Curved surface area:</u>

  • S = 2πrh = 2*5*πh = 10*44 = 440 cm²

Correct choice is C

1/5+3/25x-3=2 3/5 it said for me to solve?
Illusion [34]

Answer: x = 45

simplify both sides of the equation.

3/25x + -14/5 = 13/5

add 14/5 to both sides.

3/25x = 27/5

multiply both sides by 25/3.

x = 45
