$\large{\underbrace{\sf{\purple{required \: solution:}}}}$

$\sf \purple{ Cylinder \: A \rightarrow \sf 4420{cm}^{3} }$

$\sf \purple{ Cylinder \: B \rightarrow \sf 4590{cm}^{3} }$

Given,

• A cylinder - Height = 13cm , diameter = 20cm .
• B cylinder - Height = 6cm , diameter = 30cm .

We need to find the volume of the cylinders.

$\boxed{ \sf \purple{FORMULAE -\pi {r}^{2}h }}$

• r = diameter/2

$\rightarrow \sf \purple{ Cylinder \: A : }$

$\rightarrow \sf \pi \times {10}^{2} \times 13$

$\rightarrow \sf 3.14 \times 100\times 13$

$\rightarrow \sf 4082{cm}^{3}$

$\rightarrow \sf \purple{ Cylinder \: B : }$

$\rightarrow \sf \pi \times {15}^{2} \times 6cm$

$\rightarrow \sf 3.14\times 225 \times 6cm$

$\rightarrow \sf 4590 {cm}^{3}$

• Cylinder is a three dimensional having two parallel bases of equal size.
• Total surface area of a cube is 6a².
• Volume of a cuboid is l×b×h.
• 1cm² = 1ml.
• 1l = 1000cm³.
• 1m³ = 100000cm³ = 1000l = 1kl (kilolitre).
