Answer 1

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.
