add all marbles together to get total number of marbles that can be drawn.

4+16+5+16+10=51 total marbles

10 of the green out of 51 or 10:51

A circular tabletop has a circumference of 94.2 inches. What is its approximate area?

kiruha [24]

Since Circumference is $C=2 \pi r$
So to get Area, you have to get the radius first:
$C=(2)3.14r$ , which is $94.2=6.28r$
Next we divide both sides by $6.28$ to get:
$Radius=15in.$
Now we have to get the area which is $A= \pi r^2$
Plug in 15 for r, you should get $A=[(3.14)(15)]^2$
Final Answer: $A=706.86in.$
