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.
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 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.
