D.

785 cu. in.

Answer 1

Answer:

c.

261.67 cu. in.

Explanation:

volume of cone = 1/ 3πr^2h

r=d/2

= 10/2=5 inches

height = 2r

2×5=10 inches

volume = 1/3×3.14×5×5×10

= 1/3×3.14×250

=261.67 cu. in.

happy to help u : )

Answer 2

Answer:

given diameter=10

radius= 5 inches

height =10 inches

vol. of cone = 1/3πr^2h

=1/3×3.14×5^2×10

=1/3×3.14×250

=261.67 inches^3
