If the length of an arc intercepted by a central angle of 1.25 radians is 32 inches, which proportion could be used to find the radius of the circle?

1.25/2π = 32/πr^2
1.25/360 = 2πr/32
1.25/2π = 2πr/32
1.25/2π = 32/2πr

Find the dimensions of the circle. area = 64π in.² r= in.

Andy wants to find the distance d across a river. he located points as shown in the figure, then use similar triangles to find that d = 223.5 feet. how can you tell without calculating that he must be wrong? tell what you think he did wrong and correct his error. round your answer to the nearest tenth if necessary. andy must have used the wrong . the distance d is actually feet.
