Answer:
(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 [tex]=\pi r l[/tex]
Therefore, the area of paper used for the 3 hats
=3 X Area of One Hat
[tex]=3 \times \pi r l\\=3 \times 3.14\times 3.3 \times 8.4\\=261.12$ Square Inches[/tex]
