What are the uses of measuring tools?
To obtain accurate measurements.
What measurements do you need to find the area and perimeter of a rectangle how would you use these measurements to find the area and perimeter of a square?
The lengths of the base and the side. You would multiply these to get the area and would double sum of the two to obtain the perimeter measurement.
What is mean by telemetering?
To obtain and transmit measurements from a distance, usually a great distance. For example, measuring the amount of moisture on the surface of the planet Mars and sending that information back to a station on earth would be an exercise in telemetering.
What is the formula to find the height of a cyl?
Here are the formulae used in calculations involving a cylinder. For volume: v = (pi)(r^2)(h) For area: s = 2(pi)(r)(h) Indications: v is volume pi is taken to be 22/7 or 3.142 r is radius h is height With the information on measurements you already have, use either formula, insert the necessary figures and you would be able to obtain the height of a cylinder. If you are not looking to solve a mathematical question, h is simply: v/(pi)(r^2) or s/2(pi)(r) Reason: Because the volume or surface area are the product of multiplication of several measurements including that of height, h, to obtain h, the volume or surface area has to be divided by all other measurements.
What is the meaning of expression with variable?
It means that it is an expression, and it contains one or more variables. An "expression" is anything that can be calculated to obtain a number. For example, all of the following are expressions: 5 1 + 2 a a + 1 2a a + b
