The formula for finding the area of a circle can be written in many ways. If the radius is given, the formula is A=πr², where A=area, π=22/7 or 3.14, and r is the radius.
If the diameter is given, then the formula is A=1/4πd², where A is the area, π is 22/7 or 3.14 and d is the diameter
Given that the diameter is 46 inches and π=22/7 or approximately 3.14, the formula we can use is A=1/4πd² where A=area, π is 22/7 and d is 46
A=1/4*22/7*46*46
A=16662.57 inches² (It is rounded to nearest hundredth)
The slope of the following equation is -5, the y- intercept is (0,-2).
Answer:
<h2>NOT</h2>
Step-by-step explanation:
Put x = 1, y = -1 and z = -2 to the equation 3x - 3y - z = 2, and check the equality:
3(1) - 3(-1) - (-2) = 3 + 3 + 2 = 8 ≠ 2
Answer:
scalene
Step-by-step explanation:
self-explanatory
Answer:
Step-by-step explanation:
(a)
perfect positive correlation.
As x increases by 1, y increases by 1
y is 1 times x
equation: y = x
(b)
perfect negative correlation.
As x increases by 1, y decreases by -4
y is 
times x
equation: y = -4x
