Answer 2

Given:-

•Metal sheets size is 1m x 1m will be required form a cylinder of height 14m and radius of base is 2m.

To Find:-

•How many metal sheets

Solution:-

we have,

• r = 14m
• h = 2m

The no. of metal sheets required the cylinder given by

$\: \: \sf \: \frac{surface \: area \: of \: the \: cylinder}{area\:of \:each \: metal \: sheet }$

Now put the values here

$\: \: \sf \: = \frac{2 \pi \: rh + 2 \pi \: {r}^{2} }{ {(side)}^{2} } \\ \\ \: \: \sf \: = \frac{(2 \times 3.14 \times 2 \times 14) + (2 \times 3.14 \times {2}^{2}) }{ {(1)}^{2} } \\ \\ \: \: \sf \: = 175.84 + 25.12 \\ \\ \: \: \sf \: = 200.96 \\ \\ \: \: \sf \: = 201 \: approximately \: required \: sheets$

Hence,required metal sheet are 201.
