Answer:
D
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
Here r = 15, thus
x² + y² = 15² , that is
x² + y² = 225 → D
18*(1/3) (or one third of eighteen) = 6 dogs
<em>p = 21</em>
Step-by-step explanation:
When you have a midsegment, the base is going to be two times as large as the midsegment. You can find the midsegment if you multiply it by two and set it equal to the base. I have attached a photo below that may help you.
This is the equation we will be using.

Now let's solve! Let's start by distributing the 2 by what's in the parentheses.

Subtract p from both sides.

Add 26 to both sides.
<u>p = 21</u>
