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.

Linear equation

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change (slope) and b is the y intercept.

Let y represent the temperature at x time.

By 9:00 a.m. the same day, the temperature was 54°F. By 9:27 a.m., the temperature was -4°F

m = (-4 - 54)/27 minutes = -2.15

The average rate of change between from 9:00 to 9:27 is 2.15°F decrease per minute
