Answer:
Area = 254.34 square centimeters
Circumference = 56.52 centimeters
Step-by-step explanation:
We will use the formula for area and circumference of a circle to solve this.
Area = [tex]\pi r^2[/tex]
Where π is the constant taken as 3.14
r is the radius, given as 9 cm
Let's substitute and find the area:
[tex]A=\pi r^2\\A=(3.14)(9)^2\\A=254.34[/tex]
Area = 254.34 square centimeters
Now, the formula for circumference is:
Circumference = [tex]2\pi r[/tex]
Where π is the constant taken as 3.14
r is the radius, given as 9 cm
Substituting, we find the answer to be:
Circumference = [tex]2\pi r = 2 (3.14)(9) = 56.52[/tex]
Thus,
Circumference = 56.52 centimeters
