For all of them just use the Pythagorean theorem which is a squared plus b squared equals c squared where c is the hypotenuse (length of the side opposite the right angle) and a and b are legs. Just plug it in and solve for the missing length. For example, 1 would be (12) squared plus (5) squared equals c squared
Simplify to get 144 plus 25=c squared
169 equals c squared
Find the square root of both sides
c=13

PLZ HELP ASAP CIRCLES PART 2

Sveta_85 [38]

For this case we have the following angle:
theta = (9/5) pi
Having the conversion we have:
theta = ((9/5) pi) * (180 / pi)
Rewriting we have:
theta = (9/5) * (180)
theta = (9/5) * (180)
theta = 324 degrees
Answer:
The angle is equivalent to:
theta = 324 degrees

What is the Area of the circle in pi units if the diameter is 6 cm?

sergejj [24]

The area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.

<h3>What is the area of the circle?</h3>

The area of the circle is the space occupied by it. It is the product of pi and square of its diameter divided by 4. The area of the circle can be given as,

$A=\pi\dfrac{d^2}{4}$

Here (d) is the diameter of the circle. The diameter of the circle is 6 cm.

$d=6$

Put this value in the above formula to find the area of the circle as,

$A=\pi\dfrac{6^2}{4}\\A=\pi\dfrac{36}{4}\\A=\pi\times9\\A=9\pi\rm\; cm$

Thus, the area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.
