Question

diego learned that one of the space shuttle fuel tanks had a diameter of 840 cm and q circumference of 2639 CM. what value did u get for π using these values and the equation for circumference C= πda) some square roots are like √4 or √25 or √121 what do the square roots of these numbers have in commonb) other square roots are like √2 or √90 or √15 what do the square roots of these numbers have in commonC) how can we prove this

Answer 1

EXPLANATION

Let's see the facts:

Diameter = 840cm

Circunference = 2639cm

The circunference of a circle is given by the following relationship:

$\text{Circunference = 2}\cdot\pi\cdot r$

Remember that Radius = Diameter/2

Isolating pi:

$\frac{Circunference}{2\cdot r}=\pi$

Switching sides:

$\pi=\frac{2639\operatorname{cm}}{2\cdot(\frac{840\operatorname{cm}}{2})}=\frac{2639\operatorname{cm}}{840\operatorname{cm}}=3.141667$
