Answer:

$455.84

Step-by-step explanation:

find area of the two halves of the circle and the rectangle

area of circle= $\pi r^{2}$

where r= 2 ft

therefore

$\pi (2)^{2}\\=12.56 ft^{2}$

area of rectangle= $w*l$

where w= 4ft and l= 5ft

therefore

$(4)(5) \\=20 ft^{2}$

add areas together

$12.566 + 20 \\=32.56 ft^{2}$

it costs $14 per square foot and there are 32.566 square feet, so multiply

$14 * 32.56 \\= $455.84$

Answer:

<4 = 63°

Step-by-step explanation:

32° + 31° = < 4 ( exterior angle of a triangle is equal to the sum of two opposite interior angles)

<4 = 63°

Using the piling method, which of the following can be constructed from polygons alone and discs alone

inna [77]

Answer:

All the mentioned can be constructed with the help of piling method. But, for construction of b and d we need a point as well.

Step-by-step explanation:

a) Yes, a cube can be formed by stacking polygons. If we stack squares one upon another, then the resulting 3-D figure would be a cube.

b) Yes, a cone that does not include the point can be made by stacking disc. If we stack discs such that the discs are arranges in descending order then the resultant 3-D figure would be a cone that does not include a point.

c) Yes, a pyramid can be formed by stacking polygons.

If we stack squares such that they are arranged in descending order of their side length and stacked by a point on the top. Then the resultant figure would be a pyramid that includes a vertex.

f) There are many types of prism. Fro example a rectangular prism can be constructed by simply stacking rectangle polygon on one another.

e) Yes, a cone can be formed by stacking disc.

We need to stack disks arranged in descending order of their radius stacked with a point on the top. The resulting figure would be a cone that includes a point.

f) Yes, a cylinder can be formed by stacking. We need to stack discs of same radius to get a cylinder.

Which of the following could be an interior angle measure of a regular polygon?

Scrat [10]

Correct answer is C.

Formula for the sum of interior angles of a regular polygon is $S_n=(n-2)180^o$ , where $S_n$ is the sum of interior angles and $n$ is the number of sides of the regular polygon. Check by substituting the given values.

The measure of an interior angle of a regular polygon is equal to $\frac{S_n}{n}$ .

The equation $\frac{S_n}{n}=\alpha$ , where $\alpha$ is the measure of the interior angle of a regular polygon, must have positive integer solution for n. Check for $\alpha=150^o$ .

$\frac{S_n}{n}=150^o
\\\frac{(n-2)180^o}{n}=150^o
\\(n-2)180^o=150^on
\\180^on-360^o=150^on
\\30^on=360^o
\\n= \frac{360^o}{30^o}
\\n=12$
