The endpoints of a diameter of a circle are a(2,1) and b(5,5). find the area of the circle in terms of pi.

The area of the circle is

Step-by-step explanation:

step 1

Find the diameter of circle

we know that

The diameter of the circle is equal to the distance AB

the formula to calculate the distance between two points is equal to

substitute the values

therefore

the diameter of the circle is

step 2

Find the area of the circle

The area of the circle is equal to

 ----> the radius is half the diameter

substitute

i believe the answer is d.

hope it you! : d

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
