What is the circumference and the area of a circle with a radius of 9.3mm.
I don't remember the equations exactly, but I know there are equations to find that. Just go an a search engine and type in "circumference equation" or "area equation" and you'll find it.
The circumference formula is:
c = pi times diameter
OR
c = 2piradius
Sorry, I don't know how to make a pi symbol on the keyboard. :)
I couldn't find the area formula... but just place 9.3 in where I said radius.
Hope I helped! :)
Thanks Willow
area of circle = pi r^2

To find the circumference of a circle, you can use the formula:
Circumference = 2πr
where "r" represents the radius of the circle, and "π" is a constant value approximately equal to 3.14159.
To find the area of a circle, you can use the formula:
Area = πr^2
where "r" represents the radius of the circle, and "π" is the same constant value as mentioned before.
Now, let's calculate the circumference and area of a circle with a radius of 9.3mm:
1. Circumference:
Circumference = 2πr
= 2 * 3.14159 * 9.3
≈ 58.37304 mm
Therefore, the circumference of a circle with a radius of 9.3mm is approximately 58.37mm.
2. Area:
Area = πr^2
= 3.14159 * (9.3)^2
≈ 270.13269 mm^2
Thus, the area of a circle with a radius of 9.3mm is approximately 270.13mm².
