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.
A radius is a dead straight line from the centre of a circle to a point on its circumference.
Circumference = 2*pi*24 = 150.796 feet to 3 dp
The formula for the area (A) of a circle is A = π r2 - where r is the radius. The diameter (d) of a circle is twice the radius. The area of circle having a diameter of 24 ft is A = π 122 = 144π = 452.39 sq ft (2dp)
NO
Area of a circle = pi*radius squared
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.
A radius is a dead straight line from the centre of a circle to a point on its circumference.
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 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).
Circumference = 2*pi*24 = 150.796 feet to 3 dp
The formula for the area (A) of a circle is A = π r2 - where r is the radius. The diameter (d) of a circle is twice the radius. The area of circle having a diameter of 24 ft is A = π 122 = 144π = 452.39 sq ft (2dp)
Circumference = 2 x pi x radius = 24 pi 2 x radius = 24 ; radius = 12 units
NO
Area of a circle = pi*radius squared
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.
