If 30 is half price, then what is full price?
You can set up this problem like this:
30 = x/2
OR
30 = (1/2)x
where x is the full price.
To solve, simply multiply each half by 2:
2(30) = 2((1/2)x)
<u>x = $60</u>

A triangles angles add up too 180 so just subtract the sum and the two angles and you are done.
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>
