The surface area of the planet is 103,184,713.4 miles².

<h3>What is the surface area?</h3>

A planet has the shape of a sphere.

The first step is to determine the radius of the planet from the circumference.

Radius = circumference / (π x 2)

18,000 / (3.14 x 2) = 2,866.24 miles

Surface area of a sphere = 4πr²

4 x 3.14 x ( 2,866.24²) = 103,184,713.4 miles²

The perimeter of a triangle is 56. The side lengths are x + 4, 3x + 7, and x + 9. What is the value of x?

Sidana [21]

<h3><u>Answer:</u></h3>

x = 7.2

<h3><u>Step-by-step explanation:</u></h3>

Perimeter: Side 1 + Side 2 + Side 3

=> x + 4 + 3x + 7 + x + 9 = 56

=> 5x + 20 = 56

=> 5x = 56 - 20

=> 5x = 36

=> x = 7.2

<h3><u>Conclusion:</u></h3>

Therefore, the value of x is 7.2.
