To solve for Z simply add 8.2 to both sides of the equation and then divide by -1.2. After doing this, remember that since you are dividing by a negative number or multiplying by a negative fraction, you must change the inequality sign.

Linda calculated that the saucer for her teacup has an area of 50.24 square centimeters. What is the saucer's circumference?

Brilliant_brown [7]

Answer:

The saucer's circumference is 25.12 centimeter.

Step-by-step explanation:

Given:

Linda calculated that the saucer for her tea cup has an area of 50.24 square centimeters.

Use 3.14 for π.

Now, to find the saucer's circumference.

So, we get the radius first by putting the formula of area:

Area = 50.24 square centimeters.

Let radius be $r.$

$Area = \pi r^2.$

$Area = \pi\times r^2.$

As given we use 3.14 for π.

$50.24 = 3.14\times r^2.$

Dividing both sides by 3.14 we get:

$16=r^2.$

Using square root on both sides we get:

$4=r$

$r=4$

Thus, the radius = 4 centimeters.

Now, to get the circumference we put formula:

$Circumference=2\pi r$

$Circumference=2\times \pi \times r$

$Circumference=2\times 3.14\times 4$

$Circumference=25.12$

Circumference = 25.12 centimeter.

Therefore, the saucer's circumference is 25.12 centimeter.
