Area of a circle = pi x radius squared
Radius of a circle is from any point on the circumference to the centre
Diameter is the distance between two points on the circumference with the line crossing the centre
So radius is half of the diameter...
In this example radius is therefore 9mm (half of 18mm)
Square this... 9x9=81
So in terms of pi the answer is 81pi
To get the full answer you would just times pi (3.14) by 81 =254.34
Answer:
Step-by-step explanation:
<u>Use the given points to find the hourly pay:</u>
- $25.20/6 = $4.20
- $16.80/4 = $4.20
<u>Correct function to show the payment for h hours is:</u>
The angles of a triangle always add up to 180°
90+45+50=185
No triangles can be constructed
An acute angle is an angle less than 90 degrees. (smaller angle)
A right angle is exactly 90 degrees. (right angle)
An obtuse angle is over 90 degrees. (larger angle)
A reflex angle is any angle of 180 degrees. (largest angle)
You wouldn't *really* need a protractor to complete your homework; you could guesstimate.
I hope this helps!
