Question

find the volume. lateral surface area and total surface area of each of the cylinders whose dimensions are ... questions no (1) is radius of the base =4.2m,height =10m​

Answer 1

Answer:

volume of cylinder=

$\pi r ^{2} h$

so volume = 22/7 × 4.2 ×4.2 × 10= 554.4 m^3

lateral surface area of cylinder=

$2\pi rh$

= 2× 22/7 × 4.2 × 10= 264 m^2

total surface area of cylinder=

$2\pi r(h + r)$

= 2×22/7 ×4.2 (10+4.2)

= 374.88 m^2
