Question

the volume of a cylinder is 150 Pi cubic centimetre and its height is 6 cm find the areas of its total surface and lateral surface

Answer 1

Volume of Cylinder = πr×rh
150π = πrrh
150 = r×r×6
√25 =r
5 = r

total surface area of cylinder = 2πr(h+r)
= 2×3.14×5(6+5) = 110×3.14
= 345.4 cm sq.

curved surface area of cylinder =2πrh
= 2×π×5×6 = 60×3.14
= 188.4 cm sq.

Answer 2

345.4cm² and 188.4cm²

Step-by-step explanation:

volume of cylinder = πr²h

150π = πr²h

150 = r×r×6

√25 = r²

5 =r

total surface area = 2πr(r+h)

=2×3.14×5(5+6)

= 110×3.14

= 345.4cm²

curved surface area = 2πrh

=2×3.14×5×6

=60×3.14

= 188.4cm²
