Afountain, 3 ft in diameter, sits in the center os a circular duck pond. the pond measures 3 ft from the fountain to its edge. what is the area of the duck pond.

Step-by-step explanation:

We know that the diameter of the fountain is 3 feet and that it is in the center of the pond.

We know that the area of a circumference is:

where r is the radius of the circumference.

further

d = 2r

Where d is the diameter of the circumference.

Then the radius of the source is 1.5 ft.

The radius of the pond is 1.5 + 3 = 4.5 ft

Finally the area of the pond is equal to the area of the ring that is shown in the image

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

1/3 + 1/5 = 8/15.
