Basically add up the given side lengths and subtract that from 180 for the triangles
The circumference formula is
C=Diameter x π=22 x π, the area formula is A=<span>π x R²
or R=</span><span>D/2=22/2=11
the answer is </span><span>d. C = 22π; A = 121π</span>
Answer:
x=-72
Step-by-step explanation:
-x/6-1=-13
add 1 to both sides
-x/6=-12
multiply 6*-12
-72
x=-72 because -72/6=-12
Answer:
1 in. : 100 mi
Step-by-step explanation:
Scale = 1 inch : 10 miles
In the scale, the quantity is Length
The relationship between length and Area is;
Area = Length * Length
So inch becomes inch^2
1 inch * 1 inch = 1 i
10 miles * 10 miles = 100
The correct option is;
1 in. : 100 mi
