Answer:
13
Step-by-step explanation:
diameter = r * 2 = 13 * 2 = 26 (diameter is double radius)
Circle area = π * r^2 = π * 169 ≈ 530.9
Answer:
186 mph
Step-by-step explanation:
Miles per hour means miles divided by hour(s), so 558/3 is 186 miles per hour.
First, we should add 1 to both sides to isolate the variable:
3x = 12
Now that x is isolated, we divide by 3:
x = 4
Area of a triangle= 1/2 (ab) (sin C)
= 1/2 (9 x 11.5) (sin 63.4)
= 46.27
