60 π 0r 188.496 cm

Given: radius = 30 cm

Formula: Circumference = 2 * pi * radius

Circumfere = 2 * π * 30 cm

= 60 π

or substitute π = 3.1416

= 60 π

= 60 ( 3.1416)

= 188.496 cm

How do you find the area radius and diameter with just the circumference?

Given that the circumference of any circle is 2 * pi * r, where pi is the mathematical constant (~3.14) and r is the radius, solving for the radius is quite simple. we'll call the circumference c: c = 2*pi*r divide both sides by 2*pi: c/(2pi) = r and then the diameter is just 2 * radius. Area = pi*(r)^2 = pi*(c/(2*pi))^2 = (c^2)/(4*pi) (~ denotes approx. value) Quick example: So if a circle has a circumference of 30cm: 30 cm= 2 * pi * r r = (30cm)/(2*pi) r = (30cm)/(2*3.14) = ~4.78 cm diameter = 2 * ~4.78 cm = ~9.56 cm area = (30 cm)^2 / (4* ~3.14) = ~71.66 cm^2 c = 30 cm, r = ~4.78 cm, d = ~9.56 cm

Diameter = 30cm so radius = 15 cm. Then Area = pi*r2 = 706.9 cm2


How do you draw the circle with radius 30cm?
