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

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

$x^{2}=100$

$x=10\ in$

What is the surface area of a rectangular prism that has a length of 9 feet, a width of 5 feet, and a height of 7.5 feet?

never [62]

A suitable formula for the surface area of a rectangular prism is ...
A = 2(LW +H*(L +W))
Filling in the given information, we have
A = 2((9 ft)*(5 ft) +(7.5 ft)*(9 ft +5 ft))
A = 2(45 ft² +(7.5 ft)*(14 ft)) = 2(150 ft²)

The surface area of the rectangular prism is 300 ft².
