Answer:

The area of a circle is equal to Pi π times the radius r squared. Substitute in the value of the radius r=12 into the formula for the area of a circle. Pi π is approximately equal to 3.14 . Raise 12 to the power of

Answer:

To find the area of a circle, we use the formula π[tex]r^{2}[/tex].

Since radius is [tex]\frac{1}{2}[/tex] of the diameter, we have 6 cm as our radius.

Next, plug in each value into the formula,

if π = 3.14 we have, 3.14 x [tex]6^{2}[/tex], 3.14 x 36 = 113.04 cm^2

if π = [tex]\frac{22}{7}[/tex] we have, [tex]\frac{22}{7}[/tex] x [tex]6^{2}[/tex], [tex]\frac{22}{7}[/tex] x 36 = 113 [tex]\frac{1}{7}[/tex] cm^2

or if we use pi itself we have, 36[tex]\pi[/tex] cm^2
