Answer:

The answer is 100π.

Step-by-step explanation:

Since the diameter of the circle is 20mm, the radius of the circle is 20/2 = 10mm.

The formula for area of a circle is π*r^2. If we substitute r for 10, we get the final answer as 100π or about 314.16.

Answer:

$\frac{ {x}^{2} }{y(x - y)} + \frac{ {y}^{2} }{ - x(x - y)}$

$\frac{ {x}^{2} }{y(x - y)} - \frac{ {y}^{2} }{x(x - y)}$

$\frac{ {x}^{2} \times x - {y}^{2} \times y}{xy(x -y)}$

$\frac{(x - y)( {x}^{2} + xy + {y}^{2}) }{xy(x - y)}$

$\frac{ {x}^{2} + xy + {y}^{2} }{xy}$

Find the slope of the line that passes through (6,5) and (2,5).

aliina [53]

Slope of line passing through two points (x1,y1 ) and (x2 ,y2 ) is given by

m= y2-y1/x2 −x1

Since the line passes through (−2,5) and (6,4)

We have

Slope(m)= 4-5/6−(−2) =− 1/8

How do I solve this equation -3.9÷1.3

yaroslaw [1]

- 3.9 / 1.3 = - 3/1 = - 3

Calculation Steps:

Conversion:

3.9 = 39/10

Unary Minus:

- 3.9 = - 39/10

Conversion:

1.3 = 13/10

Divide:

- 39/10 : 1.3

= - 39/10 * 10/13

= - 39 * 10/ 10 * 13

= - 390/130

= - 3

Answer: - 3
