You can use trigonometry to find the height of the triangle. Then just use the well-known formula: area = (1/2) times base times height. You can also use Heron's Formula, which works for any triangle, if you know the three sides.

The idea is to use the equation for the area of a triangle, replace the variables you know (in this case, area and base), and solve the resulting equation for that which you don't know (in this case, the height).

Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).

Use the area formula for the triange: area = (1/2) x base x height, replace the numbers that you know, and solve.

You have to use trig. If the base angle is a and base b, the height is b tan(a).

There are several formulae for triangles; which one you use might depend on what data is given. One of the simplest one is to multiply 1/2 times the base length times the perpendicular height. If you know the three lengths of the triangle, you can use Heron's formula, which is quite a bit more complicated.

Volume is Base times height. Multiply the area of the base of the object (use Pi times the square of the radius) times the height.

You can use the formula V = (1/3) × b^2 × h, where b is the base length of the square pyramid and h is the height of the pyramid. This formula calculates the volume of a square pyramid by taking one-third of the base area multiplied by the height.

Use the Pythagorean Theorem (a2 + b2 = c2, where a and b are the legs and c is the hypotenuse) and then you will know the base of the rectangle (which would be a or b, depending on which you use). Then you can multiply the base and height to find the area of the rectangle!Great answer!
