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:
8.3
44444 is the answer
Step-by-step explanation:
Answer:
I'm hoping the answer should be D. 9 units.
Step-by-step explanation:
always remember : the sum of all angles in every triangle is always 180°.
therefore, when we get 2 angles, we can calculate the third. in our case
180 - 71 - 19 = 90
so, the third angle is 90°.
and that makes the triangle a right-angled triangle. or short : right triangle.
so, C is the right answer.
The answer is 8. you are basically adding 13 to -5. so it would be 13-5=8.
