Answer:

Option A

Step-by-step explanation:

Formula for area of circle = \pi r^2

Formula for area of trapezoid =\frac{base1+base2}{2}*height

Formula for area of triangle = \frac{base*height}{2}

Formula for area of rectangle = Length * width

\pi is an irrational number

The formula for area of circle contains \pi an irrational number which results in an irrational number

so option A is correct

Answer:  The formula for the area of a circle.


Step-by-step explanation:

1. The formula for calculate the area of a circle is:

A=r^{2}\pi

Where r is the radius of the circle.

2. By definition, the number π is an irrational number, because it cannot be expressed as a simple fraction. Therefore, if you want to calculate the area of a circle, the result will be an irrational number.

3. Then, the answer is the first option.

Parallelogram R S T U is shown. Angle S is 70 degrees.
olya-2409 [2.1K]

Answer:

<h3>B. m∠R = 110°, m∠T = 110°, m∠U = 70°</h3>

Step-by-step explanation:

The opposite angles of the parallelogram are the same.

From the diagram;

<S = <U and <R = <T

Given

<S = 70°

Since <S = <U, hence <U = 70°

Since the sum of angles in a quadrilateral is 360 degrees, hence;

<R+<S+<T+<U = 360

Since <R = <T, then;

<Y+<S+<T+<U = 360

2<T + 70+70 = 360

2<T = 360-140

2<T = 220

<T = 220/2

<T = 110°

Since <T = <R, then < R = 110°

Hence m∠R = 110°, m∠T = 110°, m∠U = 70°. Option B is correct

X Y. Determine whether y varies directly with x If so find the constant vartion k and write the equation
kirza4 [7]

Answer:

6.4 = k*4

k = 6.4 / 4

k = 1.60

11.2 = k * 7

k = 11.2 / 7

k = 1.60

16 = k * 10

k = 16/10

k = 1.60

20.8 = k * 13

k = 20.8/13

k = 1.60

Step-by-step explanation:

hope this helps! so sorry if it doesn't try not to stress over school please<3
