If there is a picture, it would be very useful, because the height and slant height are two sides of a right triangle. A good picture would show that the bottom side of this triangle is half the side length of the square. This is a leg of the right triangle: A=12' The hypotenuse of the triangle is the slant height: C=46' The "unknown" height is the other leg of the right triangle: B=? The pythagorean theorem A2+B2=C2 gives 144sqft+B2=2116sqft Solving for B gives B=44.4' Therefore, the height of the pyramid is 44.4 feet.

The slant height of a cone is given by the formula , where r is the radius of the circle and h is the height from the center of the circle to the apex of the cone.It is trivial to see why this formula holds true. If a right triangle is inscribed inside the cone, with one leg of the triangle being the line segment from the center of the circle to its radius, and the second leg of the triangle being from the apex of the cone to the center of the circle, then one leg will have length h, another leg will have length r, and by the Pythagorean Thereon, r2 + h2 = d2, and gives the length of the circle to the apex of the cone.

The formula for the area of a triangle is: A=b*(1/2)h Where A is area, b is the base, and h is the height. So for your question, the expression gives the height of 6 and a base of n. Replacing these in the formula gives you: A=n*(1/2)6 A=3n, after reducing.

There are 10mm in a centimetre. Therefore to convert the perimeter, you multiply by 10. This gives you 1000 (i.e.100x10)mm

The Sine function (abbreviated sin) takes an angle and gives a ratio which is based on the sides of a right triangle. If you have a right triangle, and one of the angles (not the right angle) is labeled y then sin y equals the length of the side opposite of angle y divided by the length of the hypotenuse. The hypotenuse of a right triangle is the longest side, and is always opposite of the right angle.

The formula for the area of a triangle is A = 1/2bh where b is the base length and h is the height. Substituting the values in the problem gives: A = 1/2(9)(14) = 63 square inches.
