An area of a circle is calculated by the formula pi(3.14) x radius^2 (squared)

This mean that you would have to type pi x 50^2 (squared) into your calculator which would equal 7853.98. Then round it up to equal 7854cm^2

In the image below, 10 is the long leg of the 30-60-90 triangle. True or false?

never [62]

The measure of the angle between the hypotenuse and the short leg is 60° and we can conclude that the side with length 10 is not the long leg of the 30 - 60 - 90 right triangle. (Right choice: False)

<h3>Is the length of a known arm in a 30 - 60 - 90 right triangle the long arm?</h3>

In accordance with geometry, the length of the long arm of a 30 - 60 - 90 right triangle is √3 / 2 times the length of the hypotenuse, the length of the short arm is 1 / 2 times the length of the hypotenuse and the length of the long arm is √3 times the length of the arm.

Thus, the measure of the angle between the hypotenuse and the short leg is 60° and we can conclude that the side with length 10 is not the long leg of the 30 - 60 - 90 right triangle. (Right choice: False)
