Answer:
92 cm
Step by step explanation:
first: you divide the rectangle into two right angled triangles using the diagonal
secondly:
you use pythagoras theorem to find the width of the rectangle
110²= 60²+ w²
w²= 110²- 60²
w²= 12100- 3600
w²= 8500
w= 92.195
w= 92 cm
Answer:
Step-by-step explanation:
If it goes 220 meters and has made 100 revolutions that means that each revolution is 220 meters / 100 = 2.2 meters.
That's the same thing as saying that the wheel has a circumference of 2.2 meters.
Circumference = 2*pi * r = pi * d
2 = pi * d
2 = 3.14 * d
2/3.14 = d
d = 0.6369 meters
Just add the side lengths together.
3x+3+2x+2+4x-1=9x+4
Y depends on x. And x are the real numbers.
Hope this helps!
