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.
