Answer:
Curved surface area =342cm^2.
Total surface area =660cm^2.
Volume =1232cm^3.
Step-by-step explanation:
Here,
it is given that,
radius of cylinder(r)=7cm
height of the cylinder(h)=8cm.
To find:
curved surfacr area, total surface area. volume
Solution:
From formula
Curved surface area of cylinder=2x22/7xrxh
2x22/7x7x8
=342cm^2.
total surface area of cylinder=2x22/7r(r+h)
=2x22/7x7(7+8)
=2x22/7x7(15)
=44x15
=660cm^2.
Volume of cylinder=22/7xr^2xh
=22/7x7x7x8
22x7x8
=22x56
=1232cm^3.
Hope it will helps in your studies
