True, if you see the picture of a triangle with altitudes, the lines are drawn on the inside. Hope that helps!)
Area = 24*Pi ft²
Area = Pi*r²
Pi*r² = 24*Pi
Canceling out Pi
r² = 24
Take square root of both sides
r = √24
r ≈ 4.899
Circumference = 2*pi*r
≈ 2*pi*4.899
≈ 2*3.141*4.899
≈ 30.78
Circumference ≈ 30.78 units.
Hope this explains it.
76 divided by 4= 19 so
Answer is 19
Answer: B x - 3y = 11 and y = -3x + 23
Explanation:
Two lines that are perpendicular have slopes that are negative reciprocals, meaning if there are lines that have slope of 2 or 2/3 or -5, lines that are perpendicular have slopes of -1/2, -3/2, 1/5 respectively.
For this question, you must make each equation in terms of y (isolate y)
A: you get -5/2x -(9/2) = y and y = -5/2x + 27/2. Here, -5/2 = -5/2 so this can’t be it. We’re looking for negative reciprocals
B: you get y = 1/3x - 11/3 = y and y = -3x + 23.
1/3 and -3 are negative reciprocals of one another so this is your answer.
