The formula you use to find the circumference of a circle is πR² or pi x radius x radius, so since your radius is 14, the answer would be A.
Answer:
the answer is 12
i used 5 12 13 special trangle
and there is 2 angle 56 and 34
so the biggest angle meet the 12
and the little angle meet the 5
hopefully its correct
Answer:
its A
Step-by-step explanation:
-37 plus 23 is - 14 which is still negative so it still to the left of the zero
Answer:
12.4=12 hours and 24 minutes
Step-by-step explanation:
D = 25 ft is the length of a shadow. L - the length of a tree.
Two angles are 85° and 65° and the third is 180° - ( 65° + 85° ) =
= 180° - 150° = 30°.
We will use the Sine Law:
25 / sin 30° = L / sin 65°
25 / 0.5 = L / 0.9063
25 * 0.9063 = 0.5 L
22.6577 = 0.5 L
L = 22.6577 : 0.5
L = 45.3 ft.
Answer: the approximate length of the tree is 45.3 ft.
