Find the area and the circumference of a circle with diameter 8yd

25.12

Step-by-step explanation:

c = 2 pi r

d = 8 so r = 4

c = 2 * 3.14 * 4

c = 25.12

Step-by-step explanation:

Given

Diameter (d) = 8 yd

radius (r) = d/2 = 8/2 = 4

Now

Area = π * r²

        = 3.14 * 4²

        = 50.24 yd²

Circumference

= π * d

= 3.14 * 8

= 25.12 yd

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
