Circumference of a Circle,C=2πr
π=3.14
r= of the circle
Area of the circle= πr²
We know that
Area= 49 π²
πr²=49
r²=49/π
=49/3.14
=15.60
r= √15.60
=3.9 units
Circumference of a Circle,C=2πr
=2*3.14*3.9
=24.492 units
The answer is 390 centimeters beacuse to get centimeters out of meters you multiple it by 100
Answer:
7x + 2y + 8

The answer is y = 3x - 2. To find slope, you subtract y2 - y1 and x2 - x1. In this case, y2 - y1 = 10 - 4 and x2 - x1 = 4 - 2. You would result in 6/2, which can be reduced to 3. Your slope is 3, so the first and second answer automatically are eliminated. Next, you could either draw it out on a coordinate plane or just visualize it. The starting point that goes through each line would be -2, which means D, or y = 3x - 2, is the correct answer.
