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
