Cam is making a party hat, shown at left, in the shape of a cone for his birthday. The circumference of the part of his head where the hat will
rest is 56 centimeters (cm). If the height of the hat is 25 cm, which of
the following is closest to the volume of Cam's hat, measured in cubic
centimeters (cm)?

V≈2,080cm^3  Hope I helped :)

Step-by-step explanation:

The volume of a cone of radius r and height h is:

V=1/3πr^2h

Since the circumference of Cam's head is 56

2πr=56

r=56/2π

r=28/π

The volume of the hat is therefore:

V=1/3π(28/π )^2(25)

V=1/3((28)^2/π)(25)

V=1/3(19,600/π)

V≈2,080cm^3

i think c. but don't trust it.

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
