Answer 1

Make an equation and solve... Well you have a rectangle area tht you dont know added to a semicircle area that you do know...
So area of a semicircle is pi r^2 all divided by 2. and you know youre r is 3.. OS the area of the semi circle is 9pi/2 ... So now add that to area of rectangle (you know the width is 3 but not the height)..So....
area of rectangle is 3h... NOw add the two and the two equal 15....
so
9pi/2 +3h=15... Solve and you get the height

Answer 2

H = 0.29?
