Hello, can anybody give answer to this question.?

Because the perimeter passes through a given point find the radius by finding the distance between that point and the origin of (0,0)

distance = sqrt((x2-x1)^2 +(y2-y1)^2)
distance = sqrt (-4-0)^2 + 3-0)^2)

distance =  sqrt(16 +9)
distance = sqrt(25)
distance = 5
 the radius of the circle is 5

 the area of a circle = PI x r^2
 area = PI x 5^2
area = PI x 25

area = 25PI
 the answer is C

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
