Question

A pipe has radius 5cm and length 10cm find the volume taking pie as 3.14

Answer 1

Answer:785cm^2

Step-by-step explanation:

r=5cm

l=10cm

Volume of pipe (cylinder)=pie×r^2×h

3.14×5^2×10=785cm^2

Answer 2

Given

• Shape of container(pipe) is cylinder.
• Radius(r) = 5cm
• Length = height(h) = 10cm
• π = 3.14

To Find

• Volume of pipe = ?

Formula

• Volume of cylinder = πr²h

Solution

$\tt \implies \: volume \: of \: pipe = \pi \: r {}^{2} h \\ \\ \tt \implies \: = (3.14 \times 5 \times 5 \times 10)cm {}^{3} \\ \\ \tt \implies = 78.5 \times 10cm {}^{3}$

$\large \implies \boxed {\boxed {\tt \blue {=785cm{}^{3} }}}$

Hence,

Volume of cylinder is 785cm³.
