an hour glass is made using identical cones double glass cones of diameter 10 centimetre each of the total height is 24 centimetre then find the surface area of the glass used in making it
Dear Student,
Please find below the solution to the asked query:
From given information we form our diagram , As :
Here , Radius of base of each cone = r = 5 cm; height of each cone = h = 12 cm
So,
Surface area of glass used = 2 ( TSA of each cone )
Hope this information will clear your doubts about Surface Areas and Volumes .
If you have any more doubts just ask here on the forum and our experts will try to help you out as soon as possible.
Regards
