Bree made three identical birthday hats out of construction paper. Each was in the shape of a cone. The diameter of each hat was

Luda [366]

Answer:

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 $=\pi r l$

Therefore, the area of paper used for the 3 hats

=3 X Area of One Hat

$=3 \times \pi r l\\=3 \times 3.14\times 3.3 \times 8.4\\=261.12$ Square Inches$

answer: m=2,n=√2

2.

sin 45=x/3

x=3/√2=3√2/2

y=3√2/2

ans:x=3√2/2,y=3√2/3

3.

sin 45=a/4

a=4/√2

b=4/√2

ans:a=4/√2,b=4/√2

b=4 base sides of isosceles triangle

sin 45=4/a

a=4√2

ans:a=4√2 and b=4
