area = pi x r^2
615.75 = 3.14 x r^2
r^2 = 615.75/3.14 =196.0987 round to 196.1
r = sqrt(196.1) = 14.00357 round to 14
radius = 14 kilometers
Answer:
52 and 45
Step-by-step explanation:
Let's call the two numbers x and y.
x+y=97
x-y=7
Let's add together the two equations:
2x=104
x=52
Since 52-y=7, y must be 45. Hope this helps!
Answer:
h = 2
Step-by-step explanation:
For the equation to have infinite solutions both sides must equate.
left side = 6x + 18
right side = h(3x + 9) substitute h = 2 , then
= 2(3x + 9) = 6x + 18 = left side
