Answer:
587.18 in²
Step-by-step explanation:
In the above question, we are given the following values
Diameter = 11 inches
Radius = Diameter/2 = 11 inches/2 = 5.5 inches
Slant height = 28.5 inches.
We were asked to find how many square inches of paper will she need to cover the ENTIRE cone.
To solve for this, we would use formula for Total Surface Area of a Cone
Total Surface Area of a Cone = πrl + πr²
= πr(r + l)
Using 3.14 for π
Total Surface Area of a Cone
= 3.14 × 5.5( 5.5 + 28.5)
= 3.14 × 5.5 × (34)
= 587.18 in²
Therefore, Anita will need 587.18 square inches of paper to cover the entire cone.

Answer:
<h3>The surface area of the prism is A prism=204m2</h3>
Step-by-step explanation:
Area is the space that is contained in a two-dimensional figure.
Surface area is the total area of all of the sides and faces of a three-dimensional figure.
To find the surface area, the area of each face is calculated and then add these areas together.
To find the area of a rectangle, multiply the length by the width .
From the graph the length of the rectangle is 10 m and the width is 8 m. Therefore, the area of the bottom face is
From the graph the length of the rectangle is 10 m and the width is 5 m. Therefore, the area of one of the rectangular side faces is
To find the area of a triangle use the following formula where b is the base and h is the height.
From the graph the base of the triangle is 8 m and the height is 3 m. Therefore, the area of one of the triangular faces is
The surface area of the prism is the sum of the area of the bottom face, the area of the two rectangular side faces, and the area of the two triangular faces
