Answer: H, 28.26
Step-by-step explanation:
Circle formula: A = πr^2
Diameter = 2r
π = 3.14 (Rounded)
1/2 of 6mm is 3mm.
3π^2 = 28.26 (I rounded)
So the correct answer is H.
I hope this helped!
<span>y - k = a(x - h)²
</span><span>y = (x − 5)² + 8 -------> y-8 = (x-5)²
</span>y - k = a(x - h)²
y - 8 = (x - 5)²
Compare these formulas we can see that k=8, h =5.
Vertex (5,8).
