If you are trying to find the area of the triangle, you would do base x height.
14 x 5
So the answer would be 70
The standard formula for the circumference (C) of a circle in terms of its diameter (d) is ...
... C = π·d
3 + 2k
This is because multiplying by 1/5 is like dividing each term by 5
The answer would be Y= 1/2x -5
