Answer:

141.37 cm

Step-by-step explanation:

If we're going off of the blue shaded region, the area of the full circle is 254.47 cm^2. Then we calculate the area of the inner circle. This gives you 113.1. Now you must subtract the area of the inner circle by the area of the outer circle. 254.47-113.1. This gives you 141.37, which should be your answer.

Factorize 9(a+1)^2-81

lora16 [44]

Answer:

The answer is 9(a-2)(a+4).

Step-by-step explanation:

Use $a^{2} -b^{2} =(a-b)(a+b)$

$9(a+1)^{2} -81= 9( (a+1)^{2}-9)= 9( (a+1)^{2}-3^{2} )= 9(a+1-3)(a+1+3)\\=9(a-2)(a+4).$

For this case we have that the point-slope equation of a line is given by:

$y-y_ {0} = m (x-x_ {0})$

Where:

m: It is the slope of the line

$(x_ {0}, y_ {0}):$ It is a point through which the line passes

In this case we have to:

$(x_ {0}, y_ {0}) :( 3,2)$

Substituting in the equation we have:

$y-2 = m (x-3)$

Answer:

$y-2 = m (x-3)$

We just need to replace the value of the slope
