We need to solve for the area of the sector.
A = n/360 * π * r²
A = 85/360 * 3.14 * 5²
A = 0.2361 * 3.14 * 25
A = 18.5347
Answer is C. 18.5 square meters.
Step-by-step explanation:

B.
{(1, 2), (1, 5), (1, –1), (1, 4)}
C.
{(–3, 4), (–2, 5), (0, 9), (0, 12)}
D.
{(8, –1), (2, –1), (3, 8), (2, 5}
The ladder leaning against the wall forms a right angled triangle with the gound and the wall. So we can use the formula:
a² + b² = c²
The ladder is the hypotenuse c²
The vertical leg is b²
The base or horizontal leg is a²
We need to find the length of the base a², so:
a² = c² - b²
a² = 5² - 4²
a² = 25 - 16
a² = 9
a = √9
a = 3
Therefore the bottom of the ladder must be 3 feet from the wall.
Mike purchased 3 DVD's and 14 video games for $203. Nick went to the same store and brought 11 DVD's and 11 video games for $220. How much is each video game and each DVD?
