A round swimming pool is a right circular cylinder, so you can use the formula pi times the radius squared times the height to calculate the volume.
Distance around circle = 2*pi*r = 157.1 so r = 157.1/(2*pi) = 25.00 ft so, to the nearest tenth of a foot, 25.0 ft
double of the radius means equal to diameter
Multiply the radius by 2, then by the value of Pi - and you'll have your answer !
Yes. Circumference is the distance around the circle, diameter is the distance across, and radius is the distance from the edge to the center.
The distance covered by the cyclist when riding halfway around a circular track with a radius of 140 meters is equal to the circumference of the circle, which is 2 * π * radius. Therefore, the distance covered would be 2 * π * 140 = 880 meters.
The radius is the distance between the centre of a circular arc and a point on the arc.
assuming the island is circular.... use the formula Area=(pi)x(radius squared) to find the radius, then use the formula C=2(pi)(radius) to determine the circumference.
Scientists measure distances around a circle using radians or degrees. Radians are the preferred unit because they provide a more direct relationship to the radius of the circle. One complete revolution around a circle is equivalent to 2π radians or 360 degrees.
The distance around the outside of a circle is called the Circumference.
what is the diameter/radius? pi times the radius squared times the height= volume pi.r^2h
The radius of a circle is the distance from the centre to the edge. The diameter is the distance right across the circle through the centre. So the diameter of a circle is always twice its radius. So if the radius of a circular CD is 6cm, the diameter is twice this - 12cm.
The radius of a circle is the distance from the center to any point on the circle's perimeter. For example, "The garden had a circular fountain with a radius of five feet."

Mars travels at somewhere around 24,000 m/s in its orbit around the sun. You can work this out by finding the distance of Mars to the Sun (the radius of orbit), finding the total distance of orbit (multiply your radius by 2*pi - assuming a circular orbit, which is ROUGHLY a good approximation), then divide by length of a Mars year. Enjoy.
