This formula is used to calculate the area of a circle using the diameter:

A= 1/4πd².

Rearrange the formula to calculate the diameter of a circle.
d = _____

Answers

Answer 1

Answer:

d= 2√a/π

     

To calculate the diameter, rewrite the formula to isolate D

Because a negative diameter doesn’t make sense, eliminate the negative answer from the solution

Simplify further to get the solution

Answer 2

The formula to calculate the diameter of the circle is d = 2 √( A/π )

where d = diameter of the circle

A = area of the circle

What is a Circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle

Given data ,

Let the radius of the circle be = r

So , the diameter of the circle = 2r

Now , the area of the circle = πr²

Substituting the value for r , we get

Area of the circle = ( 1/4 ) πd²

So , A = ( 1/4 ) πd²

Now , solving the equation for diameter of circle d , we get

Multiply by 4 on both sides of the equation , we get

πd² = 4A

Divide by π on both sides of the equation , we get

d² = 4A/π

Taking square roots on both sides of the equation , we get

d = 2 √A/π

Therefore , the value of d is 2 √A/π

Hence ,

The formula to calculate the diameter of the circle is d = 2 √( A/π )

where d = diameter of the circle

A = area of the circle

What is the answer to 8x + 4( 4x - 3) = 4( 6x + 4) - 4

Answers

Answer:

x=24

Step-by-step explanation:

8x + 4(4x - 3) = 4(6x + 4) - 4

8x + 16x - 12 = 24x + 16 - 4

24x - 12 = 24x + 12

24x = 24x + 12 + 12

24x = 24x + 24

24x/24x = 24

x = 24

Answer:

0

Step-by-step explanation:

8x + 4(4x - 3) = 4(6x + 4) - 4

8x + 16x - 12 = 24x + 16 - 4

24x - 12 =  24x + 12

-24x                  -24x

      -12 = 12

(a).

Answers

Answer:

Translate figure X [tex]\left[\begin{array}{ccc}1\\0\\\end{array}\right][/tex], reflect figure X in the y-axis to give figure Y.

Step-by-step explanation:

It is very clear that shape X is being reflected in the y-axis to give shape Y. However, when reflecting shape X, it doesn't perfectly align with Y (it is off by 1 square).

So, we need to move shape X by 1 square so that when reflected in y-axis, it will align perfectly with shape Y. We can do this using a translation. We can see that if we move shape X one square to the right and no squares up or down, it will be reflected to give shape Y in the y-axis.

This leaves us with the column vector [tex]\left[\begin{array}{ccc}1\\0\\\end{array}\right][/tex]. And our final step is to write about the reflection that we identified earlier.

So the final answer is : Translate figure X [tex]\left[\begin{array}{ccc}1\\0\\\end{array}\right][/tex], reflect figure X in the y-axis to give figure Y.
