This isn't to diffuclt. So, to the formula for the area of a circle is
, or instead of r, you can put D, which is r times 2
The diameteris 2.5, so, the answer would be
pi times 2.5, where pie = 3.14
So, the answer is 2.5 * 3.14 = 7.85 or 7.9

To find out if the angle T = 40.4 ° we use the cosine theorem.
According to the cosine theorem:
Where 
is the angle between a and b.
In this case:
Then we clear α from the formula and verify that it is equal to 40.4 °
