PLEASE HELP
Circle A has a diameter of 1 foot. Circle B has a circumference of 1 meter. Which circle is bigger? Explain your reasoning. (1 inch = 2.54 centimeters)

Circle B is bigger than Circle A.

Step-by-step explanation:

The explanation is shown below:

1. The formula that is used to calculate the circumference of a circle is:

c=2d

where d is the diameter.

2. Therefore, you can solve for the diameter to calculate the diameter of Circle B:

db=C/2

db=1m/2

db=0.5m

3. We know that 1 meter is 3.28 feet, therefore 0.5 meters is half 3.28 feet:

db=3.28ft/2=1.64ft

4. As you can see, the diameter of Circle B is bigger, therefore, Circle B is bigger than Circle A.

450 is the final answer! : )

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
