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
Step-by-step explanation:
Let the number be x. Then x + 10 = 20.
This is all you need to write out. But, for practice, find the solution as well.
X=43 ANS. FOR THE FIRST NUMBER.
43+1=44 ANS. FOR THE SECOND NUMBER.
43+2=45 ANS. FOR THE LARGEST NUMBER.
PROOF:
43+44+45=132
132=132
I dont think its possible to be 5 inches
also it depends on the time of day
