Question

a cylinder has two hemispherical and having radius 14 cm and height 50ck find the total surface area also find the curved surface area rs 5 per m2 find the cost of the colour​

Answer 1

Answer:

The total surface area of whole figure is 43.9 in meters and the cur

Answer 2

Step-by-step explanation:

Given, Radius=14cm

and height=50cm

Total surface area of cylinder

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

=2×22/7×14 (14+50)

=1282sq cm

Now, curved surface area of cylinder

$= 2\pi \: rh$

2×22/7×14×50

=4,400sq cm

Cost of the colour in m= 4400/10000×5

=2.2sq m
