40.249 rounded would be 40.2
Length of one side times how many sides there are .P= S x N
Answer:
D
Step-by-step explanation:
(r + 10)(r - 4)
To double check:
r * r is r^2
10 * r = 10r; -4 * r = -4r
Combine to get 6r.
-4 * 10 = -40
The general form for a circle centered at (a,b) with radius r is
(x - a)² + (y - b)² = r²
Comparing to our form we have a = -3, b=4, r²=25 so r=5
Answer: Center (-3,4) radius 5
