A cone has the diameter of 15 inches and is 27 inches tall what is the volume for the cone?
suter [353]

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
