2.515

Step-by-step explanation:

1. First you add the equation for a cone and a half sphere

(1/3*pi*r^2*h) + (1/2*4/3*pi*r^3)

2. You replace h with 2*r2 because height is 2*Diameter

(1/3*pi*r^2*r2) + (1/2*4/3*pi*r^3)

3. You make the equation equal 100

(1/3*pi*r^2*r2) + (1/2*4/3*pi*r^3) = 100

4. Solve for

r=2.515
