$810 ÷ 3 = 270 square feet
Area of the room is 270 square feet.
Area = 270 square feet, length = 18 feet
Area = Length x Width
270 = 18 x width
Width = 280 ÷ 18
Width = 15 feet
The room is 15 feet wide.
Answer:
the volume of a cone = 1589.625feet³
Step-by-step explanation:
given that the diameter of the cone = 15inches
radius = 15inches/2 = 7.5inches
height of the cone = 27 inches
volume of the cone = ?
recall that
the formulae for finding the volume of a cone is given to be
= 1/3πr²h
the volume of a cone = πr² h/3
the volume of a cone = 3.14 × ( 7.5)² × 27/3
the volume of a cone = (3.14 x 56.25 x27)/3
the volume of a cone = 4768.875/3
the volume of a cone = 1589.625feet³
