Answer:
90.25π
Step-by-step explanation:
The circumference of circle is 2πr, or in other words the diameter times π.
The area of a circle is πr^2.
19π is the circumference of this circle.
So, 19 is the diameter, and 9.5 the radius.
The area if (9.5^2)π.
9.5^2=90.25
So, in terms of π, the area of the circle is 90.25π.
Step-by-step explanation:
2 × (First Angle + Second Angle) = 360°
5x + 9x + 26 = 360°/2
14x + 26 = 180°
14x = 180 - 26
14x = 154
x = 154/14
x = 11°
The answer is B.
Divide the two numbers. The equation is 420/15=28. So Lee would get 28 miles per gallon of gasoline. I hope this helps!
