Answer: the circles radius is 2
The equation for circumference of a circle is 2*pi*r
And the equation for the area of a circle is pi*r^2
The only way both of these equations can be true is if 2r(pi)=(pi)r^2
Or
2r=r^2
And when is the square of a number equal to two times the number? When the number is 2
So the radius must be 2
Multiple of two has a 50 percent chance. greater than 15 is 25 percent. if both it's 10 percent
Hey there,
The geometric mean of 4 and 9 is

Reason: The square root of the product of the both numbers.
The geometric mean<span> of </span>4 and 9<span> is 6. </span>4<span> * </span>9<span>. = 6

In order for us to easily answer this problem, let us make the units uniform. So 1 kiloliter is equivalent to 10 hectoliters. This would mean that 11 kiloliters is 110 hectoliters. Since 40 hectoliters is for making ice cream, only 70 hectoliters of milk is left to be used in other ways. Hope this answers your question. Have a great day!
