The circumference of the table is 12<span>π, or about 37.7. this is because the formula for circumference is d</span><span>π (diameter x pi) the area is about 36</span>π, or about 113.1. this is because the equation for area of a circle is πr<span>² (pi x radius-squared) so, the radius of the circle is 6, since the radius is half the diameter. we put this in for "r" and have </span>π6<span>² (pi x 6-squared) 6</span><span>² = 36. we can either leave it in pi or multiply it to get the rounded answer. :)</span>
The equation for area is pi times r^2. Here the diameter is 12, so the radius would be 6. (Diameter is twice the radius.) Substituted this is pi times 6^2. The area for the picnic table is about 113.097 ______________________________________
The equation for circumference is 2 times pi times r. Substitute, 2 times pi times 6. The circumference is about 37.699
