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,
Where S is the surface area
r is the radius
and 
is the slant height
First, we will calculate the slant height of the cone
(<em>Pythagorean theorem</em>)
∴ The slant height is 10.6 ft
Now, for the surface area
S ≅ 285.01 ft²
Hence, the surface area of the given shape is 285.01 ft²

Answer: $4 per yard
Step-by-step explanation:
From the question, we are informed that Liane is sewing new curtains for her bedroom and that she bought 3 yards of fabric and her total cost was $12.
Her cost per yard will be the amount she bought the fabric divided by 3. This will be:
= $12 / 3
= $4 per yard
To find the volume of any cube you need to know the length, width and height. The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times.
To figure out long it took for Ingrid to walk her dog,multiply 3*1 and 1/2 or 3*1.5 to get 4.5 hours or 4 and 1/2 hours.
