The formula for calculating the area of a circle is 'pi r squared,' where 'r' represents the radius of the circle. A radius of a circle is, of course, half its diameter. Therefore, divide the diameter (24) by 2, then square it, then multiply that figure by pi. Twenty-four divided by two is twelve. Twelve squared is 144. So, multiply 144 by pi and 'Bob's your uncle.'
