Answer:
100°
Step-by-step explanation:
The sum of the angles in a triangle is 180°
180°-30°-50°=100°
We Know, Circumference of Circle = 2πr
Here, r = 18
Substitute it in to the expression,
C = 2π(18) = 36π
So, your final answer is 36π
Hope this helps!
Answer:
7 m
Step-by-step explanation:
Circumference of a circle uses the formula;
Circumference = 2 × pi × radius(r)
If the circumference = 44
then we use the formula above to calculate the value of the radius,
44 = 2 × pi × r...then divide both sides by (2 × pi(3.14))
Radius = 44 ÷ ( 3.14 × 2)
;Radius = 7.01
;Radius = 7m
Answer:
Option 3 is right
Start at the origin. Move 3 and one-half units down because the x-coordinate is Negative 3 and one-half. Negative 3 and one-half is between -3 and -4. Move 2 units right because the y-coordinate is -2.
Hope this helps:)
