113ft
Step-by-step explanation:
the formula πr^2 would be used as (6^2×π=113.1)
Two million, nine thousand three hundred forty five
Answer:
5.7 cm
Step-by-step explanation:
Triangle
Measurements: 9 cm, 14 cm, y cm
14 cm/2= 7 cm
a²+b²=c²
7²+b²=9²
49+b²=81
-49 -49
b²= 32
b= 5.656854249
y= 5.7
Answer:
39.91 degrees.
Step-by-step explanation:
Formula
Sin(A)/a = Sin(B) / b
Givens
Solution
Sin(84)/31 = Sin(B)/20
20*Sin(84) / 31 = Sin(B)
Sin(B) = 0.6416
B = 39.91 degrees.
====================
This looks like it is right, but you should check. Let h be the height opposite angle A.
h/20 = sin(39.91)
h = 20*sin(39.91)
h = 12.83
31 has to be longer than that amount (which it is.) So there is one solution.
