x > 14 will not create a triangle.
Answer:
200.96
Step-by-step explanation:
A = πr²
A = 3.14 x 8²
A = 3.14 x 64
A = 200.96
Answer:
x=6
Step-by-step explanation:
22x-2=20x+10
22x-20x=10+2
2x=12
x=6
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
