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.

Hich equation can pair with x + 2y = 5 to create an inconsistent system?

timofeeve [1]

X+ 2y=5
X=5-2y

2x+4y=3
2(5-2y)+4y=3
10-4y+4y=3
10=3

5x+2y=3
5(5-2y) +2y=3
25-10y+2y=3
-8y=-22
Y=-22/-8

Y=2.75

6x+12y=30
6(5-2y)+12y=30
30-12y+12y=30
30=30

3x+4y=8
3(5-2y)+4y=8
15-6y+4y=8
-2y=8-15
-2y=-7
Y= -7/-2
Y= 3.5

I need to find the surface area. it's a cut sphere with a diameter of 14.

alex41 [277]

Given data:

The diameter of the cut sphere, D=14 in.

The radius of the cut sphere is,

$\begin{gathered} r=\frac{D}{2} \\ r=\frac{14}{2} \\ r=7\text{ in} \end{gathered}$

The cut sphere is called a hemisphere.

The surface area of a sphere is

$A_1=4\pi r^2$

So, the lateral surface area of a hemisphere is half the surface area of sphere. Therefore, the lateral surface area of a hemisphere is,

$\begin{gathered} A_2=\frac{4\pi r^2}{2} \\ A_2=2\pi r^2 \end{gathered}$

The hemisphere has a lateral surface and a circular surface. The area of the circular surface is,

$A_3=\pi r^2$

Therefore, the total area of the hemisphere is,

$\begin{gathered} A=A_2+A_3 \\ A=2\text{ }\pi r^2+\pi r^2 \\ A=3\text{ }\pi r^2 \end{gathered}$

The total surface area of a hemisphere is,

$\begin{gathered} A_{}=3\text{ }\pi r^2 \\ A=3\text{ }\pi\times7^2 \\ A=461.8in^2 \end{gathered}$

Therefore, the total surface area of the cut sphere is 461.8 square inches.
