Given:
A circle with diameter 9 cm.
To find:
The area of the circle.
Solution:
The area of a circle is:
...(i)
Where r is the radius.
We know that, the diameter of a circle is twice than its radius.
The diameter of the given circle is 9 cm.
Substituting 
in (i), we get
Therefore, the area of the given circle is 63.6.
16 because the neg next to the subtraction sign becomes positive then you’re just adding 14+2.
Answer:
Car price= $36900
Sales tax 8.25%= $36900 x 8.25% = $3,044.25
Total fees= $1000
Cost of car= 36900+ 3044.25 +1000 = $40,944.25
x = 80
the sum of the angles round a point is 360°
the 3 angles here must sum to 360°
3x + x - 27 + 67 = 360
4x + 40 = 360
subtract 40 from both sides.
4x = 360 - 40 = 320
divide both sides by 4
x = 
= 80
thus the 3 angles are 67°, 240° and 53°
