What is linear foot of 18ft diameter circle?

User Avatar

Asked by Wiki User

A linear foot is the same as a foot. So, an 18-foot diameter circle would measure 18 linear feet in diameter!

Formula for volume of triangular prism?

User Avatar

Asked by Wiki User

To find the volume of a triangular prism, find the area of one of the triangles (base of the prism) first (base x height divided by 2). When you have the area of the triangle, then multiply the area of the triangle by the height of the prism, *not the height of the base.

Could the segments 9 4 and 11 form a triangle?

User Avatar

Asked by Wiki User

Yes, the sum of any two sides is always greater than the third side:

9 + 4 > 11

4 + 11 > 9

11 + 9 > 4

What do rhinoceroses look like?

User Avatar

Asked by Wiki User

A rhino is a large (1500kg-3500kg), grey, thick skinned (paciderm) mammal. It has a maximum height of around 1.7 metres and is around 4 metres long. The rhino's head is long and elongated with eyes at about mid-point between its nucal hump (neck muscle) and lips with relativaly large ears.On the front of the rhinos skull are two horns, the one in front is much larger than the second. This animal is found through out southern Africa and India. The rhino is an odd-toed ungulate with short stuby looking legs and can gain speeds of up to 35km an hour.

What is a congruent point?

User Avatar

Asked by Wiki User

The point at which there establishes one to one correspondence between two entities is ideally the 'congruent point'. ex: Two line segments are congruent if they have the same length, two angles are congruent if they have the same measure, two polygons are congruent if all the corresponding sides and angles are equal.

How it can be proved that angle between two straight lines is equal to the angle between their normals?

User Avatar

Asked by Wiki User

If two lines have angles theta1 and theta2 relative to some third arbitrary line, then the angle between those two lines is theta1 minus theta2. The normal of a line at a point is a line that is 90 degrees from the line going through that point, so the angle between a line and its normal is 90 degrees. As a result, the angle between the two normals of those lines is (theta1 plus 90) minus (theta2 plus 90), which is the same as theta1 minus theta2 because the two plus 90's cancel each other.

Describe the role of each of the following in predicting molecular geometries a unshared electron pairs by double bonds?

User Avatar

Asked by Wiki User

Lone electron pairs give the geometry a triangular base, while double bonds make the molecular geometry bent or angular.
