The circle will be enlarged by a scale factor of 4.

sertanlavr [38]

Answer:

The area of the new circle is $144\pi \ in^2$

Step-by-step explanation:

Given:

radius of the circle = 3 in.

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared.

Let

z-----> the scale factor

x-----> the area of the enlarged circle

y-----> the area of the original circle

So;

$z^2= \frac{x}{y}$

In this problem we have

$z=4$ ----> the scale factor

The area of the original circle is equal to

$y = \pi r^2= \pi (3)^2= 9\pi \ in^2$

Now substituting value of y and solve for x we get;

$4^2=\frac{x}{9\pi}\\ \\x= 16\times9\pi= 144\pi \ in^2$

Hence Area of the new Circle is $144\pi \ in^2$

Also The area of the enlarged circle is 16 times the area of the original circle.

-8m+14+9m=-5 what does this simplifies to

svetlana [45]

Answer:

m=−19

Step-by-step explanation:

Let's solve your equation step-by-step.

−8m+14+9m=−5

Step 1: Simplify both sides of the equation.

−8m+14+9m=−5

(−8m+9m)+(14)=−5 (Combine Like Terms)

m+14=−5

Step 2: Subtract 14 from both sides.

m+14−14=−5−14

m=−19

Answer: m=−19
