Whats the radius of a circle with circumference 30 cm?
To find the radius of a circle with a circumference of 30 cm, we can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given C = 30 cm, we can plug this value into the formula and solve for r. 30 = 2πr r = 30 / (2π) r ≈ 4.77 cm Therefore, the radius of the circle is approximately 4.77 cm.
How many cubic centimeters are in a one eighth inch tube one foot long?
There are 2.26 cu.cm in the tube given by you. The steps are as follows: Convert the dimensions given in inches and foot to cms.(12 inches=30 cm =1 foot) find the volume using the formula 3.14*r*r*h that gives the answer

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
