Hello!
The formula for finding area of a circle is: π · r²
Diameter is 2x the radius. To find the radius when the diameter is given, divide the diameter by 2.
The diameter is 13. 13 ÷ 2 = 6.5
r = 6.5
6.5² = 6.5 × 6.5 = 42.25
π = 3.14
Multiply 3.14 by 42.25 to get the area
3.14 × 42.25 = 132.665
<em>The area of the circle is 132.665 sq. units, which is the last option.</em>
Answer:
Piece one would equal to 14" and piece two would be 42" because 42 is three times the length of 14
The answer is 7. if you go ahead and add 6+5 you will get 11 and if you take away 4 you are left with 7. hope this helps. :)
