Question

A cylindrical tank has a capacity of 6160 cubic cm. find is depth if its radius is 14 metre

(take π=22/7)​

Answer 1

Answer:

As the unit of volume given in the question is too small so considering it 6160 m³

Volume of cylindrical tank = π r²×h

⇒6160= π×(14)²×h

⇒h = 10 m

now, the area of curved surface= 2π r×h =2π ×14×10 =880 m²

cost of painting that surface = Rs 3×880 = Rs 2640

Answer 2

${\huge{\pink{\underbrace{\overbrace{\mathbb{\blue{ANSWER:-}}}}}}}$

Volume of cylinder= 6160cm³ = 0.00616m³

Radius= 14m

Volume of cylinder=πr²h

So,

0.00616= $\frac{22}{7}$×14×14×h

0.00616= 22×2×14h

0.00616= 616h

h=0.00616/616

h=0.00001m

h=0.001cm
