    Can someone help me solve this tricky definite integral?

    It seems I did just forget the notation for dx in my equation. However, I solved using with dx in my original equation. That link you posted is useful for calculating the area of the circlular segment as well, but it does not take a calculus approach in order to solve it. It simple takes the...

    Can someone help me solve this tricky definite integral?

    I am trying to find the integral to this equation in order to obtain the cross section of a circle that has a radius = 2 and is filled with water up to 1.5. For some reason, no matter what I do I cannot find the correct solution to this integral. Solving it myself I obtain: ∫√(4-(x-2)^2)...

    Buoyant Force of sand and steel

    Thanks I substituted the equations for Wm and Wc into the Fb formula: 225.63 N = (V * 7.82 g/cm^3 * 9.8 m/s^2) - (V * 1.6 g/cm^3 * 9.8 m/s^2) I came up with the answer 3.7 m^3. Can anyone confirm if this is right or whether I just got a lucky answer close to the real one? The answer I was...

    Buoyant Force of sand and steel

    I am just not too sure how to start this equation. The answer was given (i.e. Vc = 3698 cm^3), but I just need to know the steps on how to get to the answer. A sand core used to form the internal surfaces of a steel casting experiences a buoyancy force of 225.63 N. What is the volume of the...
