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 any circle is one-half the diameter.
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.
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)
If the diameter of the circle is 24 feet, then the radius is 12 feet.
Circumference = 2 x pi x radius = 24 pi 2 x radius = 24 ; radius = 12 units
NO
Area of a circle = pi*radius squared
Area of a circle = pi times 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.
