Question

A cylinder tank has a capacity of 6160 cube metre. Find the depth

Answer 1

Answer:

Step-by-step explanation:

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
