Bree made three identical birthday hats out of construction paper. Each was in the shape of a cone. The diameter of each hat was 6.6 inches and the slant height was 8.4 inches. How many square inches of construction paper did Bree need to make the three hats? Use 3.14 for Pi and round your answer to the nearest hundredth. (Recall the formula L A = pi r l) 87.04 in2 174.08 in2 261.12 in2 522.24 in2

(C)261.12 Square Inches

Step-by-step explanation:

The diameter of the Cone Hat = 6.6 inches

Radius = Diameter/2=6.6/2=3.3 Inches

The slant height = 8.4 inches.

To determine how many square inches of construction paper did Bree need to make the three hats, we find the Curved Surface Area of the Cones.

Curved Surface Area of a Cone

Therefore, the area of paper used for the 3 hats

=3 X Area of One Hat
