Code: Select all
on mouseUp
-- calculate radius of cone in feet
put 6 into treeHeight
put 4 into treeBase
put treeBase / 2 into radius
-- calculate cone volume in cubic feet
put radius * radius * pi * treeHeight / 3 into coneVolume
-- calculate surface area of cone in square feet
put radius * radius * pi + radius * pi * sqrt(radius^2 + treeHeight^2) into coneSurfaceArea
-- calculate number of needles using surface area and needles per square foot
put coneSurfaceArea * 1000 into needleCount
answer "There are approximately " & round(needleCount) & " needles on your Christmas tree."
end mouseUp
