The surface area of a cylinder is:
A=2pr^2+2prh and since r=d/2
A=2p(d^2/4+dh/2)
A=(p/2)(d^2+2dh) and we need 200 of these cylinders...
A=(100p)(d^2+2dh), and using d and h, 3.5cm and 70cm we get:
A=(100p)(3.5^2+2*3.5*7)
A=(100p)(12.25+49)
A=6125p cm^2
A≈19242 cm^2 (to nearest cm^2)
Answer: The correct order of the options is 4, 3, 2, 1 and 5.
Explanation:
The steps for analyzing mathematical models are,
To analyzing a mathematical model first we have to defined the problem and identify parameters.
The second step is, defined the data needed. it means determine that which type of data is required according to the problem and parameters and neglect the relevant data.
The third step is collect or gather needed data. To solve the defined problem we need the related data.
The fourth step is arrange or analyse the data according to the requirements.
THe fifth step is after analysing the data draw a reasonable conclusion.
Therefore, the correct order of the options is 4, 3, 2, 1 and 5.
An exponent is a number written above and to the right side of a value or number in math. The value or number is called the base, and the expression is read out as;
"Base raised to the power of exponent."
An example is given below;
In this example, 10 is the base and 3 is the EXPONENT.
The expression is now read out as,
"10 raised to the power of 3"
Note that even unknown values (such x as we commonly use in math) can also be an exponent or base. For example, we can have;
So basically, an exponent indicates the number of times a number is used to multiply itself.
