Andi walks at a rate, r, of 4 miles per hour. what is the distance, d, that she walks in the time, t, of 3 hours? remember: d =rt (distance = rate times time)

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
