Answer:
x = 12
Step-by-step explanation:
The ray from the vertex to the base is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
=
( cross- multiply )
3x = 36 ( divide both sides by 3 )
x = 12
Answer:
The circumference of the circle is 28.26 m.
The area of the circle is 63.585 .
Step-by-step explanation:
To solve for the circumference of the circle, start by using the circumference formula of a circle, which is . However, 3.14 will be used instead of
for this formula.
First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.
Next, plug in the radius into the formula, and the formula will look like . Then, solve the equation, and the answer will be 28.26 m.
To solve for the area of the circle, start by using the area formula of a circle, which is . However, 3.14 will be used instead of
for this formula.
For the area, plug the radius into the formula, and the formula will look like . Then, solve the equation, and the answer will be 63.585
