Answer: I don’t have my calculator on me but I’ll explain
Step by step: the shape is a cone and a sphere so the volume of a sphere is 4/3 πr^3 but because it’s half a sphere, divide by 2 and the volume of a cone is 1/3h πr^2
Sphere= 4/3 π(10)^3 (plug that in ur calculator) then divide by 2
The equation of a circle is (x-h)^2+(y-k)^2=r^2, where (h,k) is the center and r is the radius. To find the radius, we would find the square root of 144, which is 12. r=12
