<span>the area of the circle :
r = 9\2
so :
S= r</span>² * Pi = (9\2)² * 3.14 = 63.58 cm²
Answer:
23°
Step-by-step explanation:
Let the missing angle be x
Reference angle = missing angle = x
Opposite side to x = 14
Hypotenuse = 36
Applying trigonometric ratio, we have:
x = 23° (to the nearest degree)
First factor out 2
2(x^4 - y^4)
Rewrite it as ((x^2)^2) and ((y^2)^2)
Then you get..
2 ((x^2)^2) - (y^2)^2))
Now both terms are perfect squares, factor using the difference of squares formula, a^2 + b^2 = (a+b)(a-b)
a= x^2 and b= y^2
2((x^2 + y^2)(x+y)(x-y))
clean it up!
2(x^2 + y^2)(x+y)(x-y)

Answer:
5,5890
Step-by-step explanation:
First we multiply the first of it by second.
Then second by third and so on. Then use hero s formula on inverse trigonometry sin cos÷56
