cross section questions

Describe the cross section of the given figure. => Square or Circle or Elipse or Rectangle..

Resistance of a conductor is inversely proportional to the area of the cross-section of the uniform wire. That means thinner the wire greater the resistance and thicker the wire lower the resistance. If A is the area of cross-section of the uniform wire, then By combining bot..

A plane that intersects a sphere is 10.5 in. from the center of the sphere. If the radius of the sphere is 17.5 in., then the area of the cross-section formed is => 296 π sq.in. or 246 π sq.in. or 196 π sq. in. or 206 π sq.in...

The base of a solid is a circle of radius 4 units. If each cross section of the solid perpendicular to the diameter AB of it is a square, then what is the volume of the solid ? => 1013 3 or 1020 3 or 1024 3 or 1016 3..

A square based pyramid of height 8 cm is resting on x -axis so that its square cross sections are perpendicular to x -axis. The vertex of the pyramid is on the plane x = 1 and the base of it is on the plane x = 5. If x is the distance from origin to the cross sect..

A golden bar of length 1.40 m and cross section 18 cm × 18 cm is used to make circular chains of length 64 cm and diameter 6 mm. How many such chains can be made? [Take π = 3.] => 2668 or 2625 or 2659 or 2811..

Cross section of an R.C.C beam is as shown. The smaller circles represent iron bars of diameter 2 cm. Find the area of the cross section covered by concrete. [Take π = 3, a = 120 cm, c = 40 cm, b = 170 cm and x = 60 cm.] => 19722 cm 2 or 20043 cm 2 or 1984..

A( x ) = ( 8 x ) is the area of cross section perpendicular to the x -axis of a solid where x is the distance of the cross section from the origin. Find the volume of the solid between the planes x = 1, x = 17 . => 17(ln 8) cubic units or 8(ln 17) cubic units..

A solid is resting on the x -axis whose cross section is perpendicular to x -axis. The area of a cross section of the solid is given by sec 2 5 x where x represents the distance of the cross section from the origin. Find the volume of the ..

If x is the distance from the origin to the cross section perpendicular to x -axis of a solid, then 12 cos x represents the area of cross section. What is the volume of the solid between the planes x = π 3 and x = π 2 ? => 6 - 6 3 or 12 - 6 3 or 12 + 6 ..
