perimeter ≈ 18.9 units ( to 1 dec. place )
Calculate the lengths of the 3 sides using the distance formula
d = √( (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(1, 1) and (x₂, y₂ ) = B(9, 2 )
d = √( (9 - 1 )² + (2 - 1 )² ) = √(64 + 1 ) = √65
repeat with (x₁, y₁ ) = B(9, 2) and (x₂, y₂ ) = C(4,5 )
d = √( (4 - 9 )² + (5 - 2 )² ) = √(25 + 9 ) = √34
let (x₁, y₁ ) = A(1, 1 ) and (x₂, y₂ ) = C(4, 5 )
d = √( (4 - 1 )² + (5 - 1 )² ) = √(9 + 16 = √25 = 5
perimeter = √65 + √34 + 5 ≈ 18.9 units
Answer:
Option 5
Step-by-step explanation:
Answer:
The answer is 8.91 or 8.9
Step-by-step explanation:
SInce the circumference is 56, you'll divide it by pi or 3.14. It's as if you're doing it backwards, but not always. After you divide it by 3.14, you'll get your diameter, or in this case, 17.8. Divide the diameter by 2 because the diameter is twice the radius. Eventually your final answer will be 8.91 or 8.9
Answer:
Step-by-step explanation: start at -39 degrees. You need to find how many degrees is between -39 and 10 degrees.
+39+10= 49 degrees risen
