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 a circle is half the diameter, so in this case, the radius of a 24-foot diameter pool would be 12 feet. The formula to find the radius from the diameter is: radius = diameter / 2. Therefore, the radius of a 24-foot diameter pool is 12 feet.
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.
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.
If the circumference is 24 the radius will be: 3.82
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
The square footage of a 24-foot circle is approximately 452.39 square feet. You can calculate this by using the formula for the area of a circle which is A = πr^2, where r is the radius of the circle (which in this case would be half of the diameter, so 12 feet).
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
A circle with a radius of 24 inches will have an area of approximately 1809.56 square inches.
