The formula for area of a circle is:
A = πr^2
where A is the area and r is the radius which is half the diameter.
Let's plug in values we know and solve:
A = 3.14(11 in)^2
A = 3.14(121 in^2)
A = 379.94 in^2
We can solve for the length of side a to the nearest whole number using the Laws of Cosines such as the formula is shown below:
a²=b²+c²-2bcCosA
Solving for the value of a, we have:
a²=10²+14²-2(10)(14)cos54°
a²=131.42
a=11.46
The answer is 11.46 or 11.5.
The answer to this will be 3 1/8
3 1/4 – 1 7/8 = 3 1/8
The general form of the equation of a straight line is ax+by+c=0
slope = -a/b
so the slope in your equation = 3
to get the y-intercept put x = 0
y = -11
the equation is y = 3x -11
you can also get it by isolating the y , it will give you the same equation
Answer:
In inches, this would be 7 inches.
Step-by-step explanation:
Your scale is 1 in.:25 mi, right?
so if we take 175 mi and divide it by 25:
175÷25=7
For so it being 7 inches on your map.
