Find the radius of a circle that has a circumference of 942 meters.

minustempo:

Do you know the formula for the circumference of a circle?

minustempo:

circumference = radius * 2pi based on this, can you figure out the radius?

Logan2020:

no

minustempo:

So you know the circumference is 942 meters 942 m = radius * 2pi so what's the radius?

Logan2020:

so do i divide it

minustempo:

you do algebra yes

Logan2020:

so raduis is 471

minustempo:

you divide by 2pi not 2

Logan2020:

would it be 1479

minustempo:

divide b 2π 942/(2π)

Logan2020:

5918.76055

Logan2020:

is that it

Jaynater:

Remember to multiply pi and 2 first before dividing 942 by the product.

Logan2020:

can u help me in dms

minustempo:

942/(2*π) = 149.924

Jaynater:

I'm here to assist, not give you the answer. Take some time to solve for the radius. Your equation has already been provided by minustempo for the formula of your circle (942 = 2πr)

Jaynater:

bruh
