Question

The drawing tip of a child’s marker is in the shape of a hemisphere. The diameter of the great circle of the hemisphere is 18 millimeters. What is the volume of the drawing tip? π cubic millimeters

Answer 1

Answer is C on Ed

Explanation:

Answer 2

pi*486mm ^3

Explanation:

The equation of a hemisphere is half of that of a sphere, therefore it is 2/3pi*radius^3

We must calculate radius, which is just diameter/2 so 18/2 or 9

We can remove pi, as you want this measured in pi cubic millimeters.

this leaves us with (2/3)*9^3 which is 486cm

Henceforth, the final answer is pi*486 cubic millimeters.
