Question

group of tibetan monks create a sand mandala at an art museum. the mandala is in the shape of circle with a radius of 2 ft. what is the area of the sand mandala? use 3.14 for π. a = ? ft² a = πr²

Explanation:

Step1: Substitute the radius into the formula

The formula for the area of a circle is \(A = \pi r^{2}\). Given \(r = 2\) ft and \(\pi=3.14\), we substitute \(r\) into the formula: \(A = 3.14\times(2)^{2}\).

Step2: Calculate the square of the radius

First, calculate \(2^{2}=2\times2 = 4\). So the formula becomes \(A = 3.14\times4\).

Step3: Multiply to find the area

Now, \(3.14\times4=(3 + 0.14)\times4=3\times4+0.14\times4=12 + 0.56 = 12.56\).

Answer:

\(12.56\)
