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 
Therefore, the area of paper used for the 3 hats
=3 X Area of One Hat

Answer:

Step-by-step explanation:
Answer:
51
Step-by-step explanation:
I mean it should add up to 180 so

Answer:
A: 6
B: 16
C: 2
D: -12
Step-by-step explanation:
They are asking you to multiply the equations:
(3x^2 + 2x - 3)(2x + 4)
Distribute and you should get:
6x^3 + 16x^2 + 2x - 12
The Coefficients A,B,C, and D are 6, 16, 2, and -12.
8p-8=-9(2p+5)-9(6-3p)
p=91
