What is the surface area of a sphere with a volume of 3000 pi m3?
First find the radius of the sphere using the volume formula, substitute volume for V & solve for r:V = (4/3)*PI*r3(3000*PI*m3 ) * (3/4) * (1/PI) = r3r3 = 2250 m3r = CUBE ROOT (2250 m3)r = 13.104 mThe surface area can now be calculated using the following formula:A = 4*PI*r2A = 4*PI*(13.104 m)2A = 686.83*PI m2

What is the volume of a sphere that has a radius of 4 inches?
Suppose the plane faces of the cylinder lie in the planes that are s units above and below the centre of the sphere. Therefore, the height of the cylinder is 2*s units. Also, by Pythagoras's theorem, the radius of the cylinder, x units, is such that x^2 + s^2 = R^2 = 16 Therefore x^2 = 16 - s^2. Volume of cylinder = pi*x^2*2*s = 2*pi*(16-s^2)*s = 2*pi*(16*s - s^3) Then dV/ds = 0 implies that 2*pi*(16 - 3*s^2) = 0 so s^2 = 16/3 and so s = 4/sqrt(3) The second derivative is -2*pi*6*s which is negative and so the volume is a maximum. When s = 4/sqrt(3), Volume of cylinder = 2*pi*[16 - 16/3]*4/sqrt(3) = 2*pi*32/3*4/sqrt(3) = 256*pi/[3*sqrt(3)] = 256*sqrt(3)*pi/9 = 49.2672*pi approx. The volume of the cylinder is approx 0.5774 times that of the sphere.
