Answer:
Sphere volume = 4/3 πr³
Hemisphere volume = 2/3 πr³
Step-by-step explanation:
Above are the formulas for volume
Where r is radius and π has value of 3.14
The volume of a hemisphere of some radius can be easily found out by calculating just half of the volume of a sphere of the same radius. Volume of hemisphere = 2πr3/3, where r is the radius of the hemisphere
75+150=225 in^2
Separate each layer.
Area1+Area2= Total area
A1= a*b*d
A2=a*c*d
A1=5*5*3=75 in^2
A2=5*10*3=150 in^2
Something happens...
Is that simultaneous equation
