The seventh-grade class is building target areas for a PE activity. The bases for the game will be in a circular shape. The diameter of each circle is 3 feet. Approximately, how many square feet of the turf need to be painted for a base circle? Use 3.14 for π and round your answer to the nearest tenth.

7.1 feet^2

Step-by-step explanation:

The base is made of a circular shape, so to solve this question we need to know how to calculate the circle area. The formula for the circle area is π  * r^2 so we need to find the radius(r). Radius equal to half of the diameter and the diameter needed is 3 feet, then the area of the circle will be:

area = π  * r^2

area = 3.14 * (3/2 feet)^2

area = 7.065 feet^2 = 7.1 feet^2

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
