The volume of the cone is a. 7,560 cm³.
Step-by-step explanation:
Step 1:
The volume of a cone is determined by multiplying with π, the square of the radius (r²) and height (h).
Here we substitute π as 3.1415.
The volume of the cone
Step 2:
The diameter of the cone is 38 cm so the radius is 19 cm. The height is 20 cm.
The volume of the cone
The volume of the cone =
The volume of the cone is 7,560.5433 cm³ which if rounded off is equal to option a.
