Find the surface area of the shape below. Round your answer to two decimal places.
marin [14]

The surface area of the given shape is 285.01 ft²

<h3>Surface area of a cone </h3>

From the question, we are to calculate the surface area of the given shape.

The given shape in the diagram is a cone.

The surface area of a cone is given by the formula,

S = \pi r(r+l)

Where S is the surface area

r is the radius

and l is the slant height

First, we will calculate the slant height of the cone

l^{2}=9^{2} +5.6^{2} (<em>Pythagorean theorem</em>)

l^{2}=81+31.36

l^{2}=112.36

l}=\sqrt{112.36}

l=10.6 \ ft

∴ The slant height is 10.6 ft

Now, for the surface area

S = \pi \times 5.6(5.6+10.6)
S = \pi \times 5.6(16.2)

S = 90.72\pi  \ ft^{2}

S = 285.0053 \ ft^{2}

S ≅ 285.01 ft²

Hence, the surface area of the given shape is 285.01 ft²

Answer:

The question asks for the number of movies that, when averaged with $100, would come down to $2.50.

Step-by-step explanation:

To elaborate more in depth, Here's an equation:

\frac{100 + 2m}{m}  = 2.5

And, if I did it correctly, the total number of movies needed would be 200
