Find the area of curved surface if area of base of cylindrical tank is $176cm^2$ and height is $30$cm.

Using the base area formula pi*r^2 = 176, the radius squared is 176 / pi, so the radius is the square root of (176 / 3.14). The curved surface area formula is 2*pi*r*h, which becomes 2 * pi * square root of (176 / pi) * 30. Calculating this gives approximately 4461.06 sq cm, which does not match any of the provided numbers.
