The diameter of a cone is 1.5 meters, the height is 1.5 times the radius, what is the volume?​
seropon [69]

Answer:

.66 cu. meters

Step-by-step explanation:

TT (pi) is 3.14

radius is 1/2 of diameter (1/2 x 1.5 =  .75 )

height is 1.5 x radius (1.5 x .75 = 1.125)

V= 1/3 x 3.14 x .75^2 x 1.125

V= .66  cu. meters
