Answer:

49π cm²

Step-by-step explanation:

Diameter (d) = 14 cm

Radius (r) = d/2 = 14/2 = 7 cm

Area of a circle

= πr²

= π × (7)²

= 49π cm²

Hope it helps ⚜

<u>Inf</u><u>ormation</u><u> provided</u><u> with</u><u> us</u><u> </u><u>:</u>

  • Diameter of the given circle is 14 cm.

<u>What</u><u> </u><u>we</u><u> have</u><u> to</u><u> calculate</u><u> </u><u>:</u>

  • Area of that circle?

<u>Per</u><u>forming</u><u> Calculations</u><u> </u><u>:</u>

Here we would be first calculating the radius of the given circle. As we know that radius of the circle is calculated by the formula,

  • r = d / 2

Putting the values,

=> r = 14 / 2

=> r = 7

Therefore, radius is of 7 cm.

Now, heading up to calculate the area of circle.

Formula,

  • A = πr²

Putting the values in the formula,

=> A = 22/7 (7)²

=> A = (22/7) × 7 × 7

=> A = 22 × 7 × 7 / 7

=> A = 22 × 49 / 7

=> A = 22 × 7

=> A = 154 cm²

If j = k, then j + 9 = k + 9 represents which algebraic property
sleet_krkn [62]

Answer:

c) The given  expression represents Addition Property of Equality.

Step-by-step explanation:

Here, the given expression is j = k

Now by ADDITION PROPERTY OF EQUALITY:

The property that states that if you add the same number to both sides of an equation, the sides remain equal.

So,  <u>  if A  = B  ⇒  A + </u><u>x </u><u> =  B + </u><u>x</u>

<u></u>

Now, here given that j = k

If we add the same number 9 on both the sides, the equation remains  undisturbed.

⇒   j + 9  = k + 9

Hence, the above expression represents Addition Property of Equality.

A circle is graphed with its center on the origin.The area of the circle is 49 square units.What are the coordinates of the x-in
neonofarm [45]

Answer:

3.95 and -3.95

Step-by-step explanation:

To graph a circle you can use the formula or (x – h)^2 + (y – k)^2 = r^2. So substituting in the given, we get x^2+y^2=49/pi. The x intercept is when y=0. So x^2=49/pi and so

x = sqrt(49/pi) and rounding to the nearest tenth, we get 3.95 and -3.95 because it isn’t a principal square root.
