Property of zero as an exponent
Answer:
78.5
Step-by-step explanation:
The formula for area of a circle is pir^2
So we have 5 for r, so r^2 would be 25.
Using 3.14 for pi, we get the answer is 78.5
The external angles of a 12-gon add up to 360 degrees so each is 30 degrees. That makes the internal angle the supplement, PQR=150 degrees.
We have an isosceles triangle so the other two angles add to 30 degrees, so 15 degrees.
Answer: 15 degrees
