What is the approximate circumference of a circle that has a center at (3,1) and passes through the point (3,6)?
1 answer:
Answer:
Approximately 31.42
Step-by-step explanation:
You use the Distance Formula
d= √( x2 - x1 )^2 + ( y2 - y1 )^2
substitute
r= √(3-3)^2 + (6-1)^2
√0^2 + 5^2
r = √25
r = 5
Now you can use the equation for finding the circumference
2πr
2π5
≈ 31.42

Answer: D
Step-by-step explanation:
Formula: A = 2(wl+hl+hw)
A = 2(5*3 + 7*3 + 7*5)
A = 2(15 + 21 + 35)
A = 2(71) = 142 sq inches
45 / 3 = 15
45 - 15 = 30
30 / 5 = 6
6 x 2 = 12
30 - 12 = 18
The answer is D:18
