Answer: C) 1963.5

Solve for area. Pi (π) is a non-algebraic number that represents the ratio of the distance around the circle (circumference) to its diameter, usually estimated as 3.14. To solve for area, square the radius (radius times radius) then multiply by 3.14.

seropon [69]

Answer:

The slope remains a constant $m=\frac{5}{3}$ as it is parallel.

Explanation:

1. Line Q is defined as a slope of $\frac{5}{3}$ ; i.e. $y=\frac{5}{3}$

2. Line R is defined to be parallel of Line Q.

3. Line Q is linear and has no domain restrictions.

The definition of being parallel requires the same slope.
