Answer:
plz ion know what is the awnser to mine
Step-by-step explanation:
Answer: The Answer is <u>A: 7.685</u> but then round it up to <u>8</u> on edge
Area of shaded region is 18π square unit.
<u>Step-by-step explanation:</u>
Given :- A circle with center O and radius 9 cm
To Find :- area of shaded region that is area of ABC
Solution : - BC = 9 cm
∠ABC = 80° = Ф
so, area of sector = πr²Ф / 360°
= (π×9×9×80) /360°
= 18π square unit
hence, area of shaded region is 18π square unit
The general equation of a line is
y= ax + b
where a is the slope
So a = -7
So y= -7x + b
But it passes through the point (5, -3)
Substitute the coordinates to calculate b:
So -3 = -7(5) + b
-3 = -35 + b
b= 35-3
b= 32
So the equation of the line of slope -7 and passing through the point (5, -3) is
y= -7x + 32
