The square is shown with a side length of 8 inches.

The area of a square is s^2, which can also be written as s x s, where a is the length of the side.

Area of the square would be 8 x 8 = 64 square inches.

The area of a circle is pi x r^2, where r is the radius. R is given as 3 inches.

The area of the circle is 3.14 x 3^2 = 28.26 square inches.

The shaded area is the square minus the circle.

The shaded area = 64 - 28.26 = 25.74 square inches.

The answer is 25.74 square inches.

Look at my explanation to know the answer clearly.

So, we're supposed to find the area of the shaded part.

In the problem, the shaded part is the square, and the side is 8 in.

Let's apply this formula, A = L · W or A². So, we can multiply the Length and Width to get the area.

The length is 8.

Since we don't have a width, we can use A². We can find 8 to the 2nd power to get the answer.

8 to the 2nd power is 64. How?

1. Break the exponent down.

8² ⇒ 8 × 8

2. Solve.

8 × 8 = 64

Hence, 64 is the answer. Hence, 64 is the answer. Now, we'll need to find the circumference of the circle.

The formula for that is 2 π r²

The radius is 3 in, so let's multiply 2 by 3² by 3.14.

3² × 3.14 = 28.26

Lastly, subtract 64 by 28.26.

64 - 28.25 = 25.74

Hence, your final answer is 25.74in.

Answer:

BD = <u>1</u> unit

AD = <u>1</u> unit

AB = <u>1.6</u> units

AC = <u>1.6</u> units

Step-by-step explanation:

In the picture attached, the triangle ABC is shown.

Given that triangle ABC is isosceles, then ∠B = ∠C

∠A + ∠B + ∠C = 180°

36° + 2∠B = 180°

∠B = (180° - 36°)/2

∠B = ∠C  = 72°

From Law of Sines:

sin(∠A)/BC = sin(∠B)/AC = sin(∠C)/AB

(Remember that BC is 1 unit long)

AB = AC = sin(72°)/sin(36°) = 1.6

In triangle ABD, ∠B = 72°/2 = 36°, then:

∠A + ∠B + ∠D = 180°

36° + 36° + ∠D = 180°

∠D =  180° - 36° - 36° = 108°

From Law of Sines:

sin(∠A)/BD = sin(∠B)/AD = sin(∠D)/AB

(now ∠A = ∠B)

BD = AD = sin(∠A)*AB/sin(∠D)

BD = AD = sin(36°)*1.6/sin(108°) = 1

I have $1000 invested in a coin worth $43000. If the coin reaches $100000 how much will I have invested?
Pavel [41]

Answer:

$2326

Step-by-step explanation:

I have $1000 invested in a coin worth $43000. If the coin reaches $100000 how much will I have invested?

To solve the above question, we have:

$43,000 = $1000

$100,000 = x

Cross Multiply

43000 × x = 100,000 × 1000

x = 100000 × 1000/43000

x = $2325.5813953

Approximately = $2326

Therefore, If the coin reaches $100000 you would have invested $2326
