Answer:

V ≈ 7850

Step-by-step explanation:

V= πr^2h is the formula

so V = 3.14 * 10^2 * 25

V = 3.14 * 2500 = 7850

depending on what decimal you use for pi, your answer will differ

If the diagonal of a square is 712, what is its area?
Setler79 [48]

The area of the square whose diagonal 712 units is 253472 units²

Step-by-step explanation:

You can find area of a square by using one of the two rules:

1. Area of a square = s², where s is the length of its side

2. Area of a square = \frac{d^{2}}{2}, where d is the length

   of its diagonal

∵ The length of the diagonal of the square is 712 units

∵ The area of the square = \frac{d^{2}}{2}

∴ The area of the square =  \frac{712^{2}}{2}

∴ The area of the square = 253472 units²

The area of the square whose diagonal 712 units is 253472 units²

What is the distance between the points (6,-7) and (1,5)
amid [387]

Answer: The distance is d = 13 .

Step-by-step explanation:

In order to find the distance between the two points, you need the distance formula:

d = \sqrt{(x_{2} - x_{1})^2 +(y_{2} - y_{1})^2} where there is (x_{1}, y_{1}) and (x_{2}, y_{2}) .

-Use the those two points (6,-7) and (1,5) for this formula:

d = \sqrt{(1 -6)^2 +(5 + 7)^2}

-Then, you start solving:

d = \sqrt{(1 -6)^2 +(5 + 7)^2}

d = \sqrt{(-5)^2 +(12)^2}

d = \sqrt{25 +144}

d = \sqrt{169}

d = 13

So, therefore, the result is d = 13 .

How are polar and rectangular planes related?
nlexa [21]

Polar coordinates (r,ϑ) and Cartesian coordinates (x,y) are related as follows:

Cartesian -> Polar
x = r cos(ϑ)
y = r sin(ϑ)

Polar -> Cartesian
r^2 = x^2 + y^2
ϑ = arctan( y/x)

The polar coo's can be extended to cylindrical by introduction a dimension z - which is perpendicular to the polar plane, it follows that:

z = z 
in between the systems (r,ϑ,z) and (x,y,z)

The polar coordinates are particularly useful when a problem has circular or cylindrical symmetry, i.e. it is usually "easier" to perform calculations on a circle (for example) using the polar coordinates.
