Answer:
The arc length of a circle is 3.14 m or 1π m
Step-by-step explanation:
First of all we have to calculate the circumference of the circle and then extract the portion that corresponds to 90°
To solve this exercise we need to use the circumference formula of a circle:
c = circumference
r = radius = 2m
π = 3.14
c = 2π * r
we replace the known values
c = 2 * 3.14 * 2m
c = 12.56m
As we know a circle is represented with 360 ° and they tell us that the angle is 90 °, so we have to know the relationship with respect to the total
90° / 360° = 1/4
Now we multiply this number by the circumference and we will obtain the length of the arc
12.56m * 1/4 = 3.14
The arc length of a circle is 3.14 m or 1π m

Answer:
Y = √(R² - X²)
Step-by-step explanation:
∵ The two forces acting at right angles to each other
∴ The resultant force R = √(X² + Y²)
∴ R² = X² + Y²
∴ Y² = R² - X²
∴ Y = √(R² - X²)

Answer:
71
Step-by-step explanation:
To find the value of x, you must subtract 38 from 180 because all triangles' angles add up to 180. Then, you get 142, so you divide 142 into 2 because the triangles is an isosceles triangle. That's how you get an answer of 71.
