Divide 10 by 2, gives you 5. multiply that by 5, 5*5= 25 then multiply that by 3.14. 25*3.14, gives you 78.5 hope this helped :D

If it has a diameter of 10, divide it by 2 to get Radius (5) because Area = πr²
Then you do r * π *r which would be 78.5. so C is your answer.

Jan had x color pencils in her box and shares them equally with her friend,Talia.Her brother gives her 2 more color pencils.Jan

liberstina [14]

3 = X/2 + 2

1 = X/2

2 = X

Jan had 2 pencils to start off with. She gave half (1 pencil) to Talia. Her brother gave her 2, which means she ends up with 3.
