Question

a group of tibetan monks create a sand mandala at an art museum. the mandala is in the shape of a circle with a radius of 0.5 m.

what is the area of the sand mandala? use 3.14 for π.

a = πr²

= ? m²

0.785
1.57
3.14
3.39

Explanation:

Step1: Identify the formula and values

The formula for the area of a circle is \( A = \pi r^2 \). We know \( \pi = 3.14 \) and \( r = 0.5 \, \text{m} \).

Step2: Substitute the values into the formula

First, calculate \( r^2 \): \( r^2 = (0.5)^2 = 0.25 \). Then multiply by \( \pi \): \( A = 3.14 \times 0.25 \).

Step3: Perform the multiplication

\( 3.14 \times 0.25 = 0.785 \).

Answer:

\( 0.785 \)
