A cylindrical glass of 6 cm hright has a radius of 3.5 cm. find the wet surface areaof the glass when water is poured into it.

Here, h = 6cm and r = 3.5 cm.
The wet surface area of the glass when water is poured into it
= Curved Surface Area of a cylindrical glass + Area of a base
= 2πrh + πr2
= 2πr (h + r)
Therefore, the wet surface area of the glass when water is poured into it is 170.5 cm2 .

- The radius of a roller is 35 cm and its length is 3 m. If it takes 30 revolutions to level a playground, find: a) the are of the playground b) the cost of levelling the ground at rs 5 per m2.
- two right circular solid cylinder have radii in the ratio 3:5 and height in the ratio 2:3.find the ratio between their:curved surface area and volume
- a closed cylindrical tank made of thin iron sheet has diameter = 8.4 m and height = 5.4 m. how much metal sheet, to the nearest sq. m, is used in making this tank, if 1/15 of the sheet actually used was wasted in making the tank
