Answer:
The length of the arc is 15.7 centimeters
Step-by-step explanation:
The central angle measures 90 degrees. In order to find the length of the arc, we need to find the total circumference of the circle.
Circumference formula = pi x diameter
The diameter is just the radius doubled
pi x (10 + 10)
pi x 20 = 62.8
The total circumference is 62.8. We know that there are 360 degrees in a circle and 90 is 1/4 of 360.
So 62.8 / 4 = 15.7
The arc should be 15.7 cm
i think this is correct, sorry if its not
Answer:
Step-by-step explanation:
D I believe because if you look at point B it is (3,3) but dilated to (9,9) and 9/3=3. Which also means that the side lengths will be 3 times the original triangle’s side lengths
