The diameter of the Sun is 1.4x 106 kilometers. (1 km = 3280 ft) What is the volume of the Sun in cubic feet?
Volume of sphere is given by:
V = 4*pi*r^3/3
r = radius of sphere
So Using given values:
r = radius of sun = diameter/2
r = 1.4*10^6 km/2 = 0.7*10^6 km
Given that 1 km = 3280 ft
r = 0.7*10^6 km*(3280 ft/1 km) = 2.296*10^9 ft
So Volume of sun will be
V = 4*pi*(2.296*10^9)^3/3
V = 5.07*10^28 ft^3

Water flows in a pipe that has a 4 ft diameter and the following hypothetical velocity distribution: The velocity is maximum at the centerline and decreases linearly with r to a minimum at the pipe wall. If Vmax = 17 ft/s and Vmin = 10 ft/s, what is the discharge in cubic feet per second and in gallons per minute? The volume flow rate is given by the integral of the velocity over the area Using the correct expression for...

The sun is 150,000,000 km from earth; its diameter is 1,400,000 km.For a science project on solar power, a student uses a 24-cm-diameter converging mirror with a focal length of 47 cm to focus sunlight onto an object. This casts an image of the sun on the object. For the most intense heat, the image of the sun should be in focus. Where should the object be placed? What is the diameter of the image? Part complete The intensity of...
