The area of a circle can be found using:
pi x r^2 (where r is the radius)
If the area of the circle is 255pi, then:
pi x r^2 = 255pi
Now we need to make r the subject:
r^2 = 255 (cancel the pi on both sides)
r = square root of 255
r = 15.96871942
Answer: 15.96871942 feet
Hope the answer helps :)
Answer :
7 unitsThere are two ways you can solve this problem:
1st way - Subtract the T's x coordinate by r's x coordinate.
1-(-6) = 1+6 =
7
2nd way - Graph the points than count the units between them.

Answer:
D. 59.66
Step-by-step explanation:
The formula is <em>A =
= 3.14</em>
so we need to find the area's
9 x 9 = 81
81 x 3.14 = 254.34
Next circle.
10 x 10 = 100
100 x 3.14 = 314
Now to find the difference.
314 - 254.34 = 59.66
59.66
