Answer:

Area : 153.86cm

Circumference: 43.96cm

Step-by-step explanation:

To Find:

Area __ cm

Circumference__ cm

Given:

Since, it given that the Diameter is 14 cm

Diameter which is any straight line segment that passes through the center of the circle.

Radius which is half of diameter

Note:

A = πr ² {Area Formula}

C = rd {Circumference Formula}

pi also known as π = 3.14 {approximately }

"r " means Radius

"d " means diameter

c = circumference

a = area

Solve:

A = πr ²

Since radius is half of the diameter then...

14/2 = 7

Radius = 7

A = 3.14(7)² { (7)² means 7 × 7 Not 7 × 2 }

A = 3.14(49) { 7 × 7 = 49}

A = 153.86

C = rd

C = 3.14(14)

C = 43.96

Area : 153.86cm

Circumference: 43.96cm

B. How was the original $20,000 investment split between the two interest rates?

Roman55 [17]

Answer:

t + f = 2000

let represent the amount invested at three percent; let f represent the amount invested at five percent. The total of these amounts is $20,000. The total of the interest earned by each amount is $800. Of course the interest earned is the amount multiplied by the interest rate.

Raquel can type 63 words every minnute.Rick type then Raquel in 135 minute?Circle the letter of the correct answer.A 1350 B 4599

lozanna [386]

Answer: 1350

Step-by-step explanation:

Here is the correct question.

Raquel can type an average of 63 words per minute. Rick can type 73 words per minute. how many more words can Rick type than Raquel in 135 minutes? Jared chose B as the correct answer. How did he get that answer? Jared said the answer is 4599. How did he get that answer?

Rick's word per minute= 73

Raquel's word per minute= 63

Ricks word in 135minute= 73×135 = 9855

Raquel's word in 135 minutes=63×135 = 8505

=9855 - 8505

= 1350

Rick can type 1350 more words than Raquel in 135 minutes.

Jared's answer is wrong. He got the answer by multiplying 63 by 73 which gives 4599.

Determine the coordinates of the point on the unit circle corresponding to the given central angle. If necessary round your resu

Olenka [21]

Answer:

Option A. (-1, 0)

Step-by-step explanation:

In the figure attached,

Circle O is a unit circle (having radius r = 1 unit)

If a point A with central angles = θ, is lying on the circle then the coordinates of the point A will be,

x = r.cosθ

x = 1.cosθ = cosθ

and y = r.sinθ

y = 1.sinθ = sinθ

Therefore, coordinates representing the point A will be (cosθ, sinθ).

As per question the given point A is lying at P (a point having central angle θ = 180°)

Coordinates of point P will be

(x', y') → (cos180°, sin180°)

→ (-1, 0)

Therefore, Option A will be the answer.
