Question

PLEASE HELPPPPPP FINDING CIRCUMFERENCE AND AREA OF A CIRCLE

Answer 1

Answer:

The circumference of the circle is 28.26 m.

The area of the circle is 63.585 $m^{2}$.

Step-by-step explanation:

To solve for the circumference of the circle, start by using the circumference formula of a circle, which is $C= 2\pi r$. However, 3.14 will be used instead of $(\pi)$ 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 $C=(2)(\pi )(4.5 m)$. 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 $A=\pi r^{2}$. However, 3.14 will be used instead of $(\pi)$ for this formula.

For the area, plug the radius into the formula, and the formula will look like $A= (3.14)(4.5m)^{2}$. Then, solve the equation, and the answer will be 63.585 $m^{2}$.
