Answer:
12.4cm
Step-by-step explanation:
Circumference of a circle: where d is the diameter.
Therefore circumference of a quarter circle (just the arc):
Arc AB = since Diameter = 2 times of Radius
Arc AB = = 12.4cm (rounded to the nearest tenth)
Answer:
put 5 then two zeros with the 5
Answer: The correct answer is Choice A (6, -1).
Since we have the slope and the equation, we can find the y-intercept and write the equation of the line.
y = -0.75x + b
5 = -0.75(-2) + b
5 = 1.5 + b
b = 3.5
Therefore, the equation is y = -0.75x + 3.5.
Now, just plug in the points until one of that satisfies the equation. The point (6, -1) will satisfy the equation.
Step-by-step explanation:
add the radii to get the diameter then multipy by pi
10 (3.14) =31.4
