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.

Determine the measure of angle bpc in the figure

Tju [1.3M]

From the last answer
angle CPD = 38°
agian,
angle BPC + angle CPD = 90° ( sum of complementary angles)
or, angle BPC + 38 = 90
or, angle BPC = 90 - 38
or, angle BPC = 52°
therefore BPC = 52
