Answer 1

ANSWER:

RADIUS: 3cm

HEIGHT:28cm

Formula for CURVED SURFACE AREA OF CYLINDER:

2πrh

Put values in formula=

$2 \times \frac{22}{7} \times 3 \times 28$

=

$2 \times \frac{22}{7} \times 84$

=

$\frac{44}{7} \times 84$

=13.3636364 cm cube

Now we will multiply area with Cost=

=13.3636364×0.6

COST OF PAINTING=8.01818184
