Question

An open cylinder tank of radius 14 cm and height 30 cm is to have its exterior surfaces painted find surface area

Answer 1

Radius of cylindrical tank , r = 14 cm

height of cylindrical tank , h = 30 cm

surface area

of tank to be painted = curved surface area + base area

surface area of tank to be painted = 2 π r h + π r²

$\tt{surface\:are\:to\:painted=2*\frac{22}{7}*14*30 + \frac{22}{7} * (14)^2}\\ \\ S.A, to\: be \:painted = 2640 + 616\\\\\tt{S.A.\:to\:be\:painted = 3256 \:cm^2$

Answer 2

Answer:

hiii Friend

Step-by-step explanation:

Radius of cylindrical tank , r = 14 cm

height of cylindrical tank , h = 30 cm

surface area

of tank to be painted = curved surface area + base area

surface area of tank to be painted = 2 π r h + π r²

Then you can solve by this.
