Circumference: 18.84 m
Area: 28.26
Explanation
For circumference, use the formula
*d, where d=the diameter(the radius times 2).
For area, use the formula 
, where r=the radius. Make sure to square the radius first before multiplying by pi!
A good way to remember these formulas is Cherry(circumference) Pi(
) is Delicious(diameter) and Apple(area)
("are too")

Answer:
6 units
Step-by-step explanation:
to calculate the distance d between the points use the distance formula
d = √(x₂ - x₁ )² + (y₂ - y₁)²
with (x₁, y₁ ) = (- 10, - 2) and (x₂, y₂ ) = (- 4, - 2)
d =
=
=
= 6
The perimeter is 10 +10+9+9 so its 38
ANSWER
The dot product is 10.
EXPLANATION
The given vectors are (2,4) and (1,2).
If we have the vectors
u=(a,b) and v=(c,d)
Then the dot product of the two vectors is given by

This implies that,

This simplifies to;
