A radius is a dead straight line from the centre of a circle to a point on its circumference.
If the diameter of the circle is 24 feet, the radius is half that, or 12 feet. If the circumference of the circle is 24 feet, the radius is 24 divided by 2 divided by pi, or 3.82 feet.
C = 2πrTherefore: (24 x 2) x 3.14 = 150.72 feet
Circumference = 2*pi*24 = 150.796 feet to 3 dp
The circumference of a circle with a 24 foot radius is 2*pi*24 = 150.8 ft (approx) The length of each brick is 12 inches = 1 foot. So 151 bricks are needed.
Volume of a cylinder = Pi x r2 x height cubic feet = 3.14 X (radius X radius) X depth 1 cubic foot = 7.48 gallons OR...... 13,529 gallons of water!
The radius of any circle is one-half the diameter.
If the diameter of the circle is 24 feet, the radius is half that, or 12 feet. If the circumference of the circle is 24 feet, the radius is 24 divided by 2 divided by pi, or 3.82 feet.
C = 2πrTherefore: (24 x 2) x 3.14 = 150.72 feet
Circumference = 2*pi*24 = 150.796 feet to 3 dp
A 24 foot circle has a radius of 12 feet. The area of a circle is pi times the radius squared. Rounded to two decimal places, that's 452.39 sq. ft.
If the circumference is 24 the radius will be: 3.82
The circumference of a circle with a 24 foot radius is 2*pi*24 = 150.8 ft (approx) The length of each brick is 12 inches = 1 foot. So 151 bricks are needed.
Volume of a cylinder = Pi x r2 x height cubic feet = 3.14 X (radius X radius) X depth 1 cubic foot = 7.48 gallons OR...... 13,529 gallons of water!
A 25-foot radius circle is 1,963.5 ft2
Radius = 1/2 of the diameter = 1/2 foot = 6 inches
It is the distance from the centre to all points on the surface of a sphere with a radius of 1 foot.
Depends whether it's the radius or diameter that's 24ft. If radius, circumference is 48pi or close to 150.8 ft; if it's diameter then circ is 24pi=75.4 ft
