1) Nashville = center = (-58, 55) => Xc = - 58miles, Yc = 55miles
2) radius = 8 miles
3) General equation of a circle: (x - Xc)^2 + (y - Yc)^2 = radius^2
4) equation of the circle that represents radar coveraga:
(x - (-58) )^2 + (y - 55)^2 = 80^2
=> (x + 58)^2 + (y - 55)^2 = 6400
Answer: (x + 58)^2 + (y - 55)^2 = 6400
Answer:
1386cm squared
Step-by-step explanation: first find the diameter.
132=pi x diameter
132=22/7xd
multiply both sides by 22/7 and you'll get 42cm
then find the area by doing this.
22/7x21x21 which gives you 1386cm squared.
the 21 is the radius.
(1454.625 mles)/(4.5 tanks) = 323.25 miles/tank
He gets 323.25 miles on a single tank of gas.
