Answer:
D. 1356.5 cm³
Step-by-step explanation:
The volume of a cone can be represented by:
V = (π)(r²)(h/3)
Substitute the known values:
π = 3.14
r = 12
h = 9
V = (3.14)(12²)(9/3)
Square 12.
V = (3.14)(144)(9/3)
Divide 9 by 3.
V = (3.14)(144)(3)
Multiply 3.14 and 144.
V = (452.16)(3)
Multiply 452.16 and 3.
V = 1356.48
Round to the nearest tenth.
V = 1356.5.
