A3 by 4 rectangle is inscribed in circle. what is the circumference of the circle? a. 2.5π b. 3π c. 5π d. 4π e. 10π

Use the Pythagorean theorem to find the radius of the circle

a²+b²=c²
3²+4²=c²
9+16=c²
25=c²
√25=c
5=c

the radius of the circle is 5, 

c=πd
c=5π

Answer=5π

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
