How do i find the radius in a circle

r=diameter/2

or r=circumference/2pi

Step-by-step explanation:

When you know the diameter: divide the diameter by 2

When you know the circumference: divide the circumference by 3.14(pi) and then divide by 2

When you know the area: divide the area by 3.14(pi) and then find the square root of that.

Hope this helps!

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
