Answer:
The circumference of a circle with radius 3 is 3 times as big as the circumference of a circle with radius 1
Explanation:
Assume that the radius of the small circle is r
Increasing the radius by a factor of 3 means that the new radius of the large circle would be 3r
Circumference of circle can be calculated as follows:
circumference = 2*π*radius
For the small circle:
circumference = 2πr
For the large circle:
circumference = 2π(3r)
circumference = 6πr
Comparing the circumference of the two circles, we can deduce the increasing the radius by a factor of 3 will lead to the increase in the circumference of the circle by factor of 3 as well

Answer:
x = 22.6°
y = 12
Step-by-step explanation:
✔️Find x using trigonometric ratio formula:
Reference angle = x
Opposite side to x = 5
Hypotenuse = 13
Thus:
(nearest tenth)
✔️Find y using Pythagorean Theorem:
Thus:
y² = 13² - 5²
y² = 144
y = √144
y = 12
