Question

if the perimeter of the base of any closed cylindrical pot is 22dm,height is 5dm. let us write by calculating the area that will be coloured to paint the outside of the pot.​

Answer 1

Answer:

$\text{Total area to be coloured is 187 dm^2 }$

Step-by-step explanation:

If the perimeter of the base of any closed cylindrical pot is 22dm,height is 5dm. let us write by calculating the area that will be coloured to paint the outside of the pot.​

Let r and h be the radius and height of the cylindrical pot respectively.

Given:

Perimeter of base of the cylindrical pot =22 dm

$\implies\:2\pi\:r=22$

$\implies\:2\times\frac{22}{7}\timesr=22$

$\implies\:2\times\frac{1}{7}\times\:r=1$

$\implies\:r=\frac{7}{2}\:dm$

Area to be coloured

= Total surface area of the cylinder

$=2\pi\:r(h+r)$

$=2\times\frac{22}{7}\times\frac{7}{2}(5+\frac{7}{2})$

$=22(\frac{17}{2})$

$=11(17)$

$=187\:dm^2$

Answer 2

the area will be coloured to paint the outside of that pot is 187dkm
