question 1
what is the exact area of a circle with a radius of 11 feet?

question 2
what is the exact area of a circle with a diameter of 18 feet?

Question 1:  379.94 ft²

Question 2: 254.34 ft²

Step-by-step explanation:

The formula for the area of a circle is:

A = πr² where r = radius of the circle

For the first question the radius = 11 feet, so plug this into the equation:

A = π(11)² = 3.14(121) = 379.94 ft²

For the second question, the diameter is 18 feet, which is two times the radius.  So, to find the radius, divide the diameter by 2:

18/2 = 9

radius = 9 feet

A = π(9)² = 3.14(81) = 254.34 ft²

the answer

b. they are parallel and will never intersect.
