Wouldn’t it be 1/5? It would go from 3/15 to 1/5 because you simplify it right?
Answer:
AC = 30 units
Step-by-step explanation:
if AB = BC, then this is an isosceles triangle.
further BX intersects the base (AC) of the isosceles triangle at a right angle.
This means that the line of symmetry BX divides triangle ABC into two congruent triangles where AX = CX.
hence AC is
AX + CX
= CX + CX
= 15 + 15
= 30 units
So hmm notice the picture below
simply get the area of the segment, and subtract it from the area of the circle, what's left, is the difference
notice your circle, has a radius "r" of 18
Sounds like a good deal to go swimming!
