Answer:
5.73cm
Step-by-step explanation:
Given parameters:
Circumference of the circle = 36cm
Unknown
Length of the radius = ?
Lets represent the radius by r
Solution
The circumference of a circle is the defined as the perimeter of a circle. The formula is given as:
Circumference of a circle = 2πr
Since the unknown is r, we make it the subject of the formula:
r = 
r =
=
= 5.73cm
Answer:
this angle is a right angle(90°)
and one of the 2 angles is 30
3x+30=90
3x=90-30
3x=60
x=20
==> B
Answer:
$154.20

= 20% * $771
= 0.2 * $771
= $154.20
The increase is $154.20
Answer:
Interior: 135 degrees
Exterior: 45 degrees
Step-by-step explanation:
The interior angle of a regular octagon is exactly 135 degrees, which can be found using the (n – 2)180 formula. The exterior is simply 180 - the interior, which is 45. :)
