8.180-65-90=25
180-80-60=40
So, 180-40-25=115.
9.(180-40)divide by 2=70
X=180-70
X=110
10.180-118=62
So, 180-62-90
=28
11.not confident yet
12.180-60=120
13. (180-66)divide by 2 =57
180-57=123
(180-123)divide by 2
=28.5
14.180-68-44=68
180-58-73=49
So,180-68-49=63
(Its the same)
Add it together, it should be 1,532,482 (I think)
Answer:
Radius of the circle = 6 units
Step-by-step explanation:
Let the radius of the circle be r
According to the given condition:
Area of the circle = 3 times the circumference of the circle
The formula for arc length is:
s= r∅
Given that ∅= 7π/4
and r= 5
Therefore, arc length s= 7π/4 *5 = 35π/4
