ok... here is what you need to do.
Pi x 6 x 6 / 2
3.14 mulitplied by 6 multiplied by 6 divided by 2
3.14 x 6 = 18.84
18.84 x 6 = 113.04
113.04 / 2 = 56.52
The formula is Pi x 6 squared / 2
I hope this helps...

the radius is 6cm therefore the area of the full circle is:
PI x (6 x 6) = 36Pi
and then you just divide the area into halves..which means the area of the half circle would be = 18Pi
i think thats how u do it...but make sure with some other math genius

1/2 x 3.14 x 6cm x 6cm
in other words, 1/2 x pi x radius squared

The answer is half the area of the whole circle. Since the area of the whole circle is pi times the radius squared, or 36*pi, the answer is 18*pi square centimeters.

The area of an entire circle is the radius squared, times "pi". So the area of half a circle is that, divided by two. One approximation for "pi" is 3.14159.

find the area of the whole circle ( pie x r x r ) usign the radius and then divide it by 2
so for ex : the radius is 6 cm
3.14 x 6 x 6
3.14 x 36
113.04
113.04 / 2
56.52

find the area of a circle, then divide by 2, the formula for the area of a circle is pi X r squared
