What is the area of the circle if XY = 5.4 mm? 5.4π mm2 7.29π mm2 10.8π mm2 14.58π mm2
Dafna1 [17]

Answer: 7.29π mm²

Step-by-step explanation:

First, I am assuming XY is the diameter of the circle :)

The formula for the area of a circle is πr² (r = radius)

So that means we need to divide the diameter by 2 to find the radius

5.4 / 2 = 2.7

Now we simply plug in our numbers!

3.14 · 2.7²

3.14 · 7.29

And that's it!

Hope this helped you :)

Represent the complex number graphically, and find the trignometric form of the number. 1 + 3i
nevsk [136]

The trigonometric form of the complex number 1 + 3i is 3.16[cos(71.57)° + isin(71.57°)]

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Complex number is in the form z = a + bi, where a, b are real numbers.

Given the complex number z = 1 + 3i

In polar form: r = √(1² + 3²) = 3.16

Ф = tan⁻¹ (3/1) = 71.57⁰

The trigonometric form of the complex number 1 + 3i is 3.16[cos(71.57)° + isin(71.57°)]
