The area of triangle ABC is?

melisa1 [442]

Answer:

$A(\triangle ABC) =17.5 \: {units}^{2}$

Step-by-step explanation:

AB = 4 - (-3) = 4 + 3 = 7 units

BC = 3 - (-2) = 3 + 2 = 5 units

$A(\triangle ABC) = \frac{1}{2} \times AB\times BC \\ \\ A(\triangle ABC) = \frac{1}{2} \times 7\times 5 \\ \\ A(\triangle ABC) = \frac{1}{2} \times 35 \\ \\ A(\triangle ABC) =17.5 \: {units}^{2}$

A princess hat for a costume is shaped like a cone. The base of the cone is 12 in across and the height is 8

LenaWriter [7]

Answer:

Part a) The drawn in the attached figure

Part b)The slant height of the outside edge is $x=10\ in$

Step-by-step explanation:

Part a) The drawn in the attached figure

Part b) What is the slant height of the outside edge?

we have that

The diameter of the base of the cone is 12 in

$r=12/2=6\ in$ ----> the radius is half the diameter

$h=8\ in$

Applying the Pythagoras Theorem find the slant height x

$x^{2}=r^{2}+h^{2}$

substitute the values

$x^{2}=6^{2}+8^{2}$

$x^{2}=100$

$x=10\ in$
