Question

please solve its really very urgent I'll make you BRAINLIST ​

Answer 1

Answer:

Let radius=r cm

Height=h=25cm

Circumference of the cylinder=132cm

2*pi*r=132

r=(132*7)/(2*22)

r=21cm

Capacity of the vessel=volume of the vessel

=pi*r^2*h

=22/7*21*21*25

=34650cm^3

=34650*1/1000 li

[since 1cm^3= 1/1000 li]

=34.65li

Hope it will help..

Answer 2

Answer:

6072 $cm^{2}$

Step-by-step explanation:

Circumference = 2πr

132 = 2 x $\frac{22}{7}$ x r

r = $\frac{132 multi. 7}{44}$

r = 924/44

r = 21

TSA = 2πr (h + r)

= 2 x $\frac{22}{7}$ x 21 (25 + 21)

= 132 x 46

= 6072 $cm^{2}$
