Calculate the approximate circumference of Earths orbit around sun, assuming that orbit is a circle with radius of 1.5 X 10 to the eighth.

What is 2PI*r?

150000000x3.14= 471,000,000

Kandice, I would switch to scientific notation, it is so much easier to read.

circumferance=2*PI*1.5E8= 940 000 000=
= 9.4E8 units

what units is radius in?

To calculate the approximate circumference of Earth's orbit around the sun, we can use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference and r is the radius.

Given that the radius of Earth's orbit is 1.5 × 10^8 (1.5 multiplied by 10 raised to the power of 8) meters, we can substitute this value into our formula to find the circumference.

C = 2πr
C = 2 × 3.14159 × (1.5 × 10^8)

Now, we can simplify the expression:

C = 2 × 3.14159 × (1.5 × 10^8)
C ≈ 9.4248 × (1.5 × 10^8)
C ≈ 14.1372 × 10^8
C ≈ 1.41372 × 10^9

Therefore, the approximate circumference of Earth's orbit around the sun is 1.41372 × 10^9 meters.
