1. ### a spherical shaped tank with r=10ft. using calculus find the volume V of the liquid in the tank?

place the origin at the center of the sphere, so the bounding curve is x² + y² = 10² take a 'slice ' of the liquid..the volume is then π radius² thickness , radius is just x , thickness is dy , where y in [-10 , h] int over y in [-10,h] of { π...

2. ### Assuming that an atom of gold is spherical in shape and has a daimeter of 0.26nm?

hmmmm...a physicist question. let's see... nanometer = 1/billionith of a meter = 1/1,000,000,000 = 1/10^9 = 1x10^-9 meters centimeter = 1/hundredth of a meter = 1/100 = 1/10^2 = 1x10^-2meters so 1 cm/.26nm/atom = 1*10^-2/.26*10^-9 = 3.85x10^7atoms ans: 3.85*10^7 atoms. good luck.

3. ### If you roll a particle of a large spherical shape , at what point would it fall off?

Assuming frictionless ideal conditions, with no rotational inertia of the particle, we let radius of the sphere = r, outward centripedal acceleration = a, velocity of the particle on the surface = v, the angle of the particle's position above horizon relative to the center of the sphere = θ, acceleration due to gravity = g, and finally the drop...

5. ### a spherical shape with a mass of about 5.869 x 10^6 kg and a volume of 6.8 x 10^12 cubic meters.?

F=m*a or Weight=Mass* Gravity A) Gravity is an acceleration and is consistent at 32.2 ft/s^2 (9.814m/s^2). The weight (the force felt) will vary based on the other acceleration factors you note (rotation). But...

7. ### A martini glass has the shape shown, and is filled with wine. A spherical ball of?

seeing no shape here. but i'm assuming the inverted right conical glass you should be showing. but i'm not answering a vague question on YA, but i'll make it my homework. later.

8. ### The radius of a balloon that is spherical in shape is decreasing at the rate of .75 yard per minute...?

Just take the time-derivative of the volume dV/dt = 4 PI r^2 * dr/dt you know dr/dt = -.75 ( decreasing) and r = 25.
