The equation T^2=A^3 shows the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A
MariettaO [177]
The given equation for the relationship between a planet's orbital period, T and the planet's mean distance from the sun, A is T^2 = A^3. Let the orbital period of planet X be T(X) and that of planet Y = T(Y) and let the mean distance of planet X from the sun be A(X) and that of planet Y = A(Y), then A(Y) = 2A(X) [T(Y)]^2 = [A(Y)]^3 = [2A(X)]^3 But [T(X)]^2 = [A(X)]^3 Thus [T(Y)]^2 = 2^3[T(X)]^2 [T(Y)]^2 / [T(X)]^2 = 2^3 T(Y) / T(X) = 2^3/2 Therefore, the orbital period increased by a factor of 2^3/2 <span>

The radius of a circle is 16 millimeters. What is the circle's area?
Kisachek [45]

Answer:

803.84 millimeters²

Step-by-step explanation:

How do we find the area of a circle?

  • The area of a circle is πr², where r = radius. In this case, we have to approximate pi to 3.14.

<u>Solving</u>

  • <u></u>3.14 *16^2
  • 3.14*256
  • 803.84

Therefore, the area is 803.84 square millimeters.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
