We can solve this system of equation by reduction method.
  d+e=15
 -d+e=-5
-------------------
      2e=10   ⇒e=10/2=5

-(d+e=15)
 -d+e=-5
-----------------
  -2d=-20   ⇒d=-20/-2=10

therefore: d=10; e=5

Answer: d.(10,5)

pantera1 [17]
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 :)
