It said that wasn't right

jhonyy9 · Answer

formula for circumference of a circle is 2*pi*r 
so than you substitute this value of r=7 in place of r inside this formula and multiply it by 2 so will get right sure the circumference of this circle with radius equal 7 feet in term of pi 

hope helped

cal44 · Answer

The formula for the circumference of a circle is C=2(pi)r
Since we know the radius r we can substitute C=2(pi)(7)
since everything is being multiplied just switch it and simply to get C=14pi
