The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle.
If a circle has a diameter of 4, its circumference is 3.14*4=12.56.
If you know the radius, the diameter is twice as large.
0.45
90/2=45% chance they will go 110/2=55% chance they won't go
Step-by-step explanation:
36A) AB = 4/ sin 30° = 4/ 0.5 = 8 cm
36B) AC = 4/ tan 30° = 4/ 0.577 = 6.9 cm
36C) BD = 4/sin 45° = 4/ 0.707 = 5.7 cm
36D) area of ∆ABC = ½×6.9×4= 13.8 cm²
36E) sin A = sin 30° = 0.5
The answer to the given expression (-7) + b = (-11) is -4
<h3>How to solve an expression</h3><h3 />
(-7) + b = (-11) = -4
-7 + b = - 11
b = -11 + 7
b = -4
