Answer:

B) 12.25πm²  

Step-by-step explanation:

The formula for the <em>circumference</em> of a circle is

C = 2πr

The circumference of your circle is

C = 7πm

If we factor out a 2 from the 7, we get

C = (2 × 3.5)πm = 2π(3.5m)

Now, if we compare the two formulas, we see that

r = 3.5m

The formula for the <em>area</em> of a circle is

A = πr²

If r = 3.5m, then the area of your circle is

A = π(3.5m)² = 12.25πm²

The endpoints of the longest chord on a circle are (4, 5.5) and (4, 10.5).
In-s [12.5K]
The longest chord on the circle is the diameter, and the center of the circle is the midpoint of the diameter.

Use the midpoint formula to find the center
((x1 +x2)/2 , (y1+y2)/2).. Just substitute them for the solution


the x-coordinates are the same, so you can just subtract the y-coordinates to find the radius. 
10.5 - 8 = 2.5

The equation of the circle is (x - h)² + (y - k)² = r² where r is the radius and (h, k) is the center.

(x - 4)² + (y - 8)² = 6.25

Which equation has the graph shown below? (0, 3) (2,0) ​
professor190 [17]

Answer:

6x+4y=12

Step-by-step explanation:

when x-intercept is 0

6(0)+4y=12

0+4y=12

divide by 4 both side

y=3

when y-intercept is 0

6x+4(0)=12

6x+0=12

6x=12

divide by 6 both side

x=2

Which step will get you closest to the solution of this equation 5×(x-2)=7
scZoUnD [109]

Answer:

Division property get you to the quick solution

Solution: 3.4

Step-by-step explanation:

5*(x - 2) = 7

Dividing both sides by 5

5*(x -2)÷5 = 7÷5

x - 2 = 1.4

Adding 2 on both sides, we

x -2 + 2 = 1.4 + 2

x = 3.4

Hope you will understand the concept.

Thank you.
