The formula to find the circumference (perimeter) of a circle:
, where
is the radius.
1) To find the circumference of the circle, we need to find the radius (
) first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.
Cancel the
by bringing it to the other side.

9 = 4
18 = 8
27 = 12
36 = 16
45 = 20
I think the answer is ( 28 degrees
Answer:
x = 6
Step-by-step explanation:
3 (2x - 5) = 21
=> 6x - 15 = 21
=> 6x = 21 + 15
=> 6x = 36
=> x = 36 / 6
=> x = 6
OR
3 (2x - 5) = 21
=> 2x - 5 = 21 / 3
=> 2x - 5 = 7
=> 2x = 7 + 5
=> 2x = 12
=> x = 12 / 2
=> x = 6
