Select a function that asks the user for a number and multiplies it by 10.

• number = float(input("Enter a number: "))

  print(number * 10)

• def multiply():

  int(input("Enter a number: "))

  print(number)

• def multiply():

  number = 10*float(input("Enter a number: "))

  print(f"The result is: {number}")

• number = input("Enter a number: ")

  print(f"The number multiplied by 10 is: {float(number)}")
