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
