Question

what is the area of the sand mandala? use 3.14 for \\(\pi\\).\\(a = \pi r^2\\)\\(= 1.57\space m^2\\)\\(a = \pi r^2\\)\\(= 3.14 \cdot (0.5)^2\\)

Explanation:

Step1: Calculate the square of the radius

The radius \( r = 0.5 \) m, so \( r^{2}=(0.5)^{2}=0.25 \) \( m^{2} \).

Step2: Multiply by π (3.14)

Using the formula \( A = \pi r^{2} \), substitute \( \pi = 3.14 \) and \( r^{2}=0.25 \). So \( A = 3.14\times0.25 = 0.785 \) \( m^{2} \).

Answer:

\( 0.785 \) square meters
