*PLEASE HELP* A metal ornament is being designed such that its perimeter is created by four identical three-quarter circles as shown whose centers are connected to form a square. The ornament, both circular and square portions, made of wire that weighs 1.8 grams per inch. The square has sides that are 4 inches long.

Answers

Questions :

(a) Determine the total length of the circular portions in terms of

pi. Show the work that leads to your answer.

(b) Determine the total length of wire needed, both circular and

square portions, to the nearest tenth of an inch.

G

(c) Determine the total weight of the ornament to the nearest

gram.

Answer:

12π

53.68 in

96.624g

Step-by-step explanation:

The total length of the circular portion :

Perimeter of circle = Circumference of the circle = 2πr ; r = radius = 2

Size of each circle is 3/4

Number of circles = 4

Number of complete circles :

4 × 3/4 = 3 complete circles

Perimeter of circle:

Number of circles * (2πr)

3 * 2 * π * 2 = 12π

Total wore needed :

Circular + Square

Perimeter of square = 4s

s=side length = 4

Total square 4 * 4 = 16

Perimeter of Square + perimeter of circle

16 + 12π = 16 + (12 * 3.14) = 53.68 in

Total weight of ornament :

1.8 g * perimeter

1.8 * 53.68 = 96.624g

Question 1 = true or false = 2

Question 2 = true or false = 2

Question 3 = true or false = 2

Question 4 = true or false = 2

x = 11

Step-by-step explanation:

Since this is a triangle, all interior angles add up to 180 so:

57 + 73 + 3x + 17 = 180

3x + 147 = 180

3x = 180 - 147

3x = 33

What is the volume of this figure?

Answers

Answer:

1920

Step-by-step explanation:

I'm just doing it my way because it feels easier, but multiply 14 x 20 x 8 to get the volume of the entire figure.

Then we subtract that box of air which is 10 x 4 x 8.

So 14 x 20 = 280

280 x 8 = 2240

Then we find the volume of the missing part which is

10 x 4 = 40

40 x 8 = 320.

We get 2240 - 320 = 1920

Remember kids, wear your masks!

1920! You multiply the cubes individually and the add it together

Gabrielle cut a square cake vertically to make two rectangle slices. Each rectangle had a perimeter of 33 inches. How long is each side of the original square cake?

Answers

Answer:

11 inches

Step-by-step explanation:

Perimeter of each rectangle = 33 inches

The square cake is cut in half

which means two half sides would equal one whole side.

2 × 1/2 = 1

The two "halves" in the smaller rectangle would equal one whole side + the two whole sides in the smaller rectangle

1 + 2 = 3

Each side of the original square cake = 33 inches / 3

= 11 inches

Each side of the original square cake = 11 inches
