\tan(51^o 33')=  \frac{200}{base1}
<span>
base1= 158.802

</span>\tan(18^o 33')= \frac{200}{base2}
<span>
base2=596.008

the distance travelled = 596.008 - 158.802 = 438 m</span>

Min knows that Pi times r = 9.42 centimeters. What would she need to do to find the area?
Alinara [238K]

Answer:

The area of the circle is 28.26.

Step-by-step explanation:

πr =9.42

Using that, we can find the radius, which will help us find the area of the circle.

9.42/π = 3 (I used 3.14 for π)

The formula for area of a circle is:

πr^2

Plug our values in.

π(3^2)

9π

28.26

The area of the circle is 28.26.

To sum, Min would need to first figure out the radius of the circle, and then use the radius to find the area of the circle. She can figure out the radius by dividing 9.42 by π, and find the area with the formula πr^2.

We notice it diviides by 3 each time or multiplies by 1/3
