To determine the circumference and area of these circles, we must use the proper formulas.
For circumference : 2PiR (or PiD, which Pi = 3.14).
For area: PiR^2
Since we have the radius, let's get to solving!
The first circle (Circle1):
Our radius is 8cm, so let's work for it's circumference. Using our formula, we will multiply 8 by 2 by 3.14.
16 x 3.14 = 50.24.
Circle1's circumference is 50.24cm^2.
Now let's do the area for Circle1.
The radius, 8, squared is (8x8) 64.
64 x 3.14 = 200.96 cm^2.
The area for Circle1 is 200.96cm^2.
Now let's work with Circle2 (second circle).
The radius for that circle is 5cm.
Let's use our circumference formula.
5 x 2 x 3.14 = 10 x 3.14 = 31.4cm^2,
Our circumference for Circle2 is 31.4cm^2.
Now let's do the area for Circle2.
3.14 x 5^2.
25 x 3.14 = 78.5cm^2.
Our area for Circle2 is 78.5.
Let's compare our circumferences and our areas.
Circle1 to Circle 2's Circumference:
50.24:31.4
If we were to divide 50.24 by 31.4 we'd get 1.6.
Circle1 to Circle2's Area: 200.96:78.5.
If we were to divide 200.95 by 78.5 we'd get 2.56.
The circles are NOT similar.

What is cos 0 when sin 0
taurus [48]

Answer:

Cos θ = √7/3

Step-by-step explanation:

From the question given above, the following data were obtained:

Sine θ = √2 / 3

Cos θ =?

Recall

Sine θ = Opposite / Hypothenus

Sine θ = √2 / 3

Thus,

Opposite = √2

Hypothenus = 3

Next, we shall determine the Adjacent. This can be obtained as follow:

Opposite = √2

Hypothenus = 3

Adjacent =?

Hypo² = Adj² + Opp²

3² = Adj² + (√2)²

9 = Adj² + 2

Collect like terms

9 – 2 = Adj²

7 = Adj²

Take the square root of both side

Adjacent = √7

Finally, we shall determine the value Cos θ. This can be obtained as follow:

Adjacent = √7

Hypothenus = 3

Cos θ =?

Cos θ = Adjacent / Hypothenus

Cos θ = √7/3

The first sentence in the chart belongs to the subjunctive mood, while the other sentences can be classified as part of the conditional mood.

<h3>What is a verb mood?</h3>

In language, the verb mood indicates the attitude of the speaker, and therefore, it provides clues about the way language is used. For example, the imperative mode indicates an order is being given.

<h3>What is the difference between the conditional and the subjunctive mood?</h3>
  • Subjunctive: It is used for expressing wishes; due to this, it is common to find the use of words such as "wish".
  • Conditional: It expresses a condition or a situation that will/can happen if another situation occurs. This can be identified due to the use of "if".

Based on this, the first sentences belongs to the subjunctive mood, while the other sentences are part of the conditional.

Mrac [35]
1. It is important to go through each of the words given in the question to get through to the actual answer. The function will be:
y= (4 * x) - 5
  = 4x - 5

2. The function of this statement will be
(h/3) + 2.5 = w

1. Let us assume the price of a pizza = p
    From the first part we can write 
    p = $6.95
    On adding the price of each topping "t" we get
    p = $6.95 + ($0.95) * t
       = <span>$6.95 + $0.95t</span>
    I hope it helps you.
