Answer:
1 and 3
Step-by-step explanation:
The formula for the volume of a cone is 1/3

r²h, where r is the radius and h is the height.
Insert the values into the equation:
1/3

(5)²(11) ≈ 287.979327 (use a calculator for this part)
Divide 287.979327 by

and convert the decimal to a fraction:
91.66666666666666666666666666666666666666... = 91 2/3
The volume of the figure is 91 2/3

cubic units or units³.
