Answer:
26.4
Step-by-step explanation:
<u>Law Of Cosines:</u>
This should work for any side. This can generally be thought as:
If this is too confusing here's the formula for the other sides (which is essentially the same, just different variables)
Anyways now just plug in the known values into the equation
Square and multiply values
Add the values in the numerator
Take the inverse of cosine on both sides
calculate arccosine (inverse cosine) using a calculator
Round to nearest tenth
Answer:
The area of circle = πR ^2
And diameter = 7 units
By interchanging d in R =d/2 = R =7/2 = 3.5
Step-by-step explanation:
<h3>πR ^2 =3.14 x (3.5)^2</h3><h3> =3.14 x 3.5 x 3.5</h3><h3> =38.465 (unit)^2

You look at the tenths place(the number behind the decimal) then you look at the the numbers behind it if the one directly behind it is more than five then you round it up one so like this would be 4.000 because u leave the number in front alone until you have figured the other things out so leave the three alone for right now the look at the nine then look at the eight it is more than five so you round the nine to ten(which would be 4) then turn everything else to zeros so the answer is 4.000 or just 4
Answer:
5,000
