Measurements of length, width and height are used to find the volume of a solid figure. Volume is measured in cubic units, because three values are being multiplied to arrive at the final figure.
Know MoreVolume formulas differ depending on the shape of the object being measured. Cones, cylinders, spheres and pyramids are measured differently from each other and from cubes or rectangular solids.
To find the volume of a cube with sides 3 inches long, multiply the length times the width times the height, 3 x 3 x 3. This gives 27, so the volume is 27 inches cubed, or 27 cubic inches.
Learn more about TrigonometryTrigonometry is used in aviation extensively, both in the calculations performed by the machines and computers used by the pilots, and by pilots performing quick rudimentary calculations and estimates themselves. Trigonometry and trigonometric functions are used to estimate distances and landing patterns and navigate around obstacles.
Full Answer >To calculate the volume of any space, measure the length, width and height of the room. Multiply the length by the width and then by the height. Measuring the volume of non-rectangular rooms is a bit more complicated, requiring the division of the room into measurable sections.
Full Answer >In the real world, sinusoidal functions can be used to describe mechanical functions such as the swinging of a pendulum or natural phenomena such as hours of daylight. Sinusoidal functions graph wave forms.
Full Answer >Some real life examples of periodic functions are the length of a day, voltage coming out of a wall socket and finding the depth of water at high or low tide. A periodic function is defined as a function that repeats its values in regular periods. The period is the length of time it takes for the cycle to repeat itself.
