165+172=337
172/337 is the experimental probability of tails.
Hope this helps!
4.56•10•10•10•10•10. The dots mean multiply
3/10 =50/x First multiply 50x10 then divide that number by 3 to get the answer
Circumference=2*pi*r or pi*d so if its 16pi you know that your diameter is 16 wich means your radius is 8 because d/2 is your radius. plug the 8 into the area formula wich gives you the formula pi*8^2. 8squared is 64. 64 times pi is 201. <span>or 64pi wich is the area of the same circle with the circumfernce of 16pi
</span>
The center is (-2,0)
The radius is -3
