1. A circular pond 16.8 meters in diameter is surrounded by a tile path 3.6 meters wide.  Find the area of the tile path.  Round to the nearest hundredth.  Use π≈3.14.

 

2.A circular pond 16.8 meters in diameter is surrounded by a tile path 3.6 meters wide. How much farther would you go if you walked along the outer edge of the path compared to the inner edge of the path?  Round to the nearest hundredth.  Use π≈3.14.

 

3. A wire bent into the shape of a square encloses an area of 36 cm2.  Then, the same wire is cut and bent into two identical circles.  What is the diameter of one of the circles?  Round to the nearest hundredth. Use π≈3.14.

 

4. two circles have radii of 28 cm and 7 cm.  The smaller circle rolls along the circumference of the larger circle until the smaller circle returns to its original position. How many revolutions will the small circle make? 

 

5.How many circles of radius 7 cm can you fit inside a circle with radius 28 cm (if you could cut up the smaller circles to tightly pack them into the larger circle with no gaps)? 

 

6.The sides of a square field are 12.8 meters each. A sprinkler in the center of the field sprays a circular area with a diameter that corresponds to the side of the field. How much of the field is not reached by the sprinkler? Round your answer to the nearest hundredth. Draw and label a picture. Use π≈3.14.

 

7. Two angles are complementary angles.  One angle measures fourteen more than three times the other. Find the measure of the larger angle.
