The formula for the circumference of a circle is c=rd, where d is the length of the diameter. If d is a rational number, what ca

dimaraw [331]

Answer: The answer is (d) It is an irrational number.

Step-by-step explanation: Given formula for circumference of a circle is

$\textup{c}=\textup{r d},$

where 'd' is the length of the diameter and a rational number.

We are to choose one of the given four options for the circumference 'c' of the circle.

We know that the circumference of a circle with diameter 'd' is given by

$\textup{c}=\pi \textup{d},$

Comparing this with the given equation, we get

$r=\pi,~\textup{where}~\pi~\textup{is an irrational number}=\dfrac{22}{7}.$

Now, the product of a rational and an irrational number is again irrational, so 'r × d' will be an irrational number.

Hence, the circumference, c = rd is irrational.

Thus, the correct option is (d) It is an irrational number.

Given PQ = 24

Verdich [7]

The shape PQRS is a parallelogram

The measure of angle QRS is 70 degrees
The measure of angle PQS is 53 degrees
The measure of angle RPS is 35 degrees
The measure of angle PSQ is 53 degrees

The given parameters are:

$\mathbf{\angle PQR = 106}$

$\mathbf{\angle QSR = 49}$

$\mathbf{\angle PRS = 35}$

(a) Find QRS

This is calculated as:

$\mathbf{\angle QRS = 2 \times \angle PRS }$

So, we have:

$\mathbf{\angle QRS = 2 \times 35}$

$\mathbf{\angle QRS = 70}$

Hence, the measure of angle QRS is 70 degrees

(b) Find PQS

This is calculated as:

$\mathbf{\angle PQS = \frac 12 \times \angle PQR }$

So, we have:

$\mathbf{\angle PQS = \frac 12 \times 106}$

$\mathbf{\angle PQS = 53}$

Hence, the measure of angle PQS is 53 degrees

(c) Find RPS

This is calculated as:

$\mathbf{\angle RPS = \angle PRQ }$

Where:

$\mathbf{\angle PRQ = \angle PRS = 35}$

So, we have:

$\mathbf{\angle RPS = 35}$

Hence, the measure of angle RPS is 35 degrees

(d) Find PSQ

This is calculated as:

$\mathbf{\angle PSQ =\frac 12 \times \angle PQR }$

Where:

$\mathbf{\angle PSQ =\frac 12 \times \angle 106}$

So, we have:

$\mathbf{\angle PSQ =53}$

Hence, the measure of angle PSQ is 53 degrees
