If the diameter is 9 cm the radius is 4.5 cm (half the diameter).  The area of a circle is given by the formula:  4πr^2, where π is the constant ratio of circumference to diameter (3.14159...).

3.14 cm x 4.5 cm = 14.13 cm^2.  Remember, the units must be squared to represent area.  14.13 is extended to the nearest hundredth.

1. n≥-9
3. n≤-63

Find the length of base PQ in the trapezoid.
iris [78.8K]

Answer:

PQ = 20

Step-by-step explanation:

Theorem:  The length of the median of a trapezoid is the average of the base lengths.

\frac{PQ + 12}{2}  = 16

PQ + 12 = 32

PQ = 20

See how easy that is if you know the theorem!
