a 3 by 4 rectangle is inscribed in circle . what is the circumference of the circle ?
"if a rectangle is inscribed in a circle , then the diagonal of the rectangle = diameter of the circle . in this case , diagonal = ( 9 + 16 ) ^ ( 1 / 2 ) = 5 hence the radius = 2.5 circumference = 2 π r = 2 π * 2.5 = 5 π correct option : c"
